This guide uses general farm-management principles and USDA resources for conservation and agricultural economics. Conditions, forage prices, emergency rules, and boarding practices vary by location. Review local requirements and confirm current hay availability, feed costs, and storm-recovery options with qualified local professionals.

After a major storm, a boarding plan can sound simple: move the horses somewhere safe, arrange feed, repair the property, and keep everyone comfortable until normal operations resume. The difficult part is often not finding a stall. It is finding enough suitable forage for the full recovery period.
Storms can flatten pasture, flood hay storage, contaminate water, damage access roads, delay deliveries, and make normal turnout unsafe. If a facility accepts additional horses without calculating its forage supply, the arrangement can become stressful and expensive for everyone.
Forage math should come before the dream of opening a temporary boarding space. The goal is not to predict every storm. It is to know how many horse-days the property can support, how much hay is actually usable, how much waste is likely, and when the supply will run out.
Why does a storm turn boarding into a hay problem?
Horses may need more hay when pasture is unavailable, muddy, damaged, or unsafe. A storm can also disrupt the supply chain at the same time that demand rises. Local farms may lose standing forage, hay fields may be too wet to harvest, and roads may be difficult for trucks.
Even when a property has a barn and empty stalls, those structures do not create feed. A temporary boarding plan must account for every horse on the property, including resident horses, boarders, visiting horses, and any animals that may arrive during the recovery period.
Hay is also not interchangeable. A horse accustomed to grass hay may not tolerate an abrupt switch to rich legume hay. Moldy, wet, heated, or flood-exposed forage can be unsafe. The available bale must meet the horse's nutritional needs and be suitable for its age, workload, health status, and dietary restrictions.
How much forage does one horse need each day?
A practical starting point is to estimate forage as a percentage of body weight, then have a veterinarian or equine nutrition professional refine the plan. Many adult horses consume forage in a broad range around 1.5% to 2.5% of body weight per day, depending on health, workload, pasture access, forage quality, and the rest of the ration.
For a 1,000-pound horse, that broad planning range equals approximately 15 to 25 pounds of forage per day. This is a planning estimate, not a universal feeding prescription. A hard keeper, an easy keeper, a growing horse, a lactating mare, or a horse with metabolic disease may require a different approach.
For emergency boarding calculations, use the horse's actual body weight when possible. If a scale is unavailable, use a reliable weight tape or a veterinarian's estimate. Do not assume every horse weighs 1,000 pounds simply because that number is convenient.
How do you convert a daily forage estimate into hay?
Start with the daily forage target, then add a realistic allowance for handling and feeding loss. Hay can be wasted through trampling, wind, rain, poor storage, aggressive feeding, and refusal of coarse or stemmy portions.
A simple formula is:
Daily hay required = daily forage target divided by the proportion of hay that is actually consumed.
If a horse is expected to consume 20 pounds per day and the feeding system results in 15% waste, the property needs more than 20 pounds delivered. The estimated requirement is 20 divided by 0.85, or about 23.5 pounds of hay per day.
Waste may be lower with careful storage and slow-feed systems, or higher when hay is placed directly on muddy ground. Use an honest local estimate. Underestimating waste is one of the fastest ways to create a mid-storm shortage.
What does one bale actually provide?
Bale count alone is not enough. Two small square bales can look similar while weighing very different amounts. Large round bales can also vary substantially by size, density, moisture, and baling method.
Weigh representative bales whenever possible. If that is not practical, ask the supplier for an average bale weight and treat the number as an estimate. Then calculate usable hay:
Usable hay per bale = bale weight multiplied by the percentage expected to be consumed.
For example, a 50-pound bale with an estimated 15% loss provides about 42.5 pounds of consumed hay. A horse consuming 20 pounds per day would use approximately half of that bale per day. A 10-day supply for one horse would require roughly five such bales under those assumptions.
Write down the assumptions. If the bales are heavier, lighter, wetter, poorer quality, or more wasteful than expected, the estimate changes.
How many horse-days does the property have?
Horse-days are a useful emergency planning unit. One horse kept for one day equals one horse-day. Ten horses kept for seven days equal 70 horse-days.
To calculate the supply:
- Estimate the daily hay requirement for each horse.
- Add the expected feeding and storage loss.
- Multiply by the number of horses.
- Multiply by the number of days the property must operate without a dependable delivery.
- Add a reserve for delays, damaged bales, and changing conditions.
Consider a property with eight 1,000-pound horses, each planned at 20 pounds of consumed forage per day, with 15% loss. The group requires about 188 pounds of hay delivered each day. For 14 days, that is approximately 2,625 pounds before adding an emergency reserve.
The reserve should be based on local risk and access. A property with one clear road and several nearby suppliers may use a different reserve than a property that regularly loses access after flooding. Confirm the appropriate reserve with local agricultural advisers and suppliers.
How should you calculate hay for mixed groups?
Do not average all horses into one convenient number if the group includes very different animals. Separate horses into practical feeding categories, such as easy keepers, average-maintenance adults, hard keepers, seniors, growing horses, and horses with medical diets.
Some horses may need restricted access while others require free-choice forage. Some may need soaked hay, low-sugar forage, or a specific grass or legume mix. A temporary boarding facility needs enough space and equipment to keep those diets separate.
Make a written list for every horse that includes estimated weight, daily forage amount, permitted hay types, supplements, medications, and feeding instructions. The owner should review the list, and medical or unusual diets should be confirmed with a veterinarian or qualified equine nutrition professional.
What hay is unsafe after a storm?
Hay exposed to floodwater should be treated as compromised. Floodwater can contain sewage, chemicals, fuel, debris, and other contaminants. Do not assume that drying makes contaminated hay safe.
Hay that is visibly moldy, musty, unusually warm, discolored, or dusty deserves careful evaluation. Heating in stored hay can indicate dangerous moisture levels and may create a fire risk. A smell test is not a complete safety assessment, and a clean-looking bale is not automatically suitable.
Keep wet hay separate from dry inventory. Do not mix questionable bales into a good stack. Document the affected supply and ask a local veterinarian, feed specialist, or agricultural professional how to handle it. Local disposal and cleanup requirements can vary, so confirm locally before burning, burying, or transporting damaged material.
Can pasture replace hay after a storm?
Pasture may help, but it should not be counted at full value immediately after severe weather. Standing forage may be flattened, covered in sediment, contaminated, overgrazed, or damaged around roots. Wet ground can increase the risk of mud-related hoof problems and soil compaction.
Inspect fences, gates, water sources, toxic plant exposure, downed limbs, standing water, and access routes before turnout. A pasture that appears green may still be unsafe. Horses should not be turned onto land with exposed wire, unstable trees, debris, or contaminated water.
Use a conservative pasture estimate until recovery is clear. If the field can provide only part of the daily forage requirement, calculate hay for the remainder. Conservation planning can help with soil protection, erosion, and recovery decisions. NRCS resources may provide useful starting information, but site-specific recommendations should be confirmed locally.
How much storage space does emergency hay require?
Storage is part of the forage calculation. Hay needs protection from ground moisture, roof leaks, runoff, and poor airflow. Bales stored directly on wet floors or soil can absorb moisture and lose quality quickly.
Before accepting boarders, inspect the storage area for leaks, ventilation, fire hazards, pest damage, and access for unloading. Keep hay away from ignition sources and follow local fire-safety expectations. Do not stack more hay than the floor, walls, or structure can safely support.
Separate hay by lot when possible. Mark the purchase or harvest date, supplier, forage type, and any known analysis. Feeding older suitable hay first can reduce spoilage, but questionable hay should not be used merely because it is already paid for.
What should a temporary boarding budget include?
The hay invoice is only one part of the cost. A responsible budget may include delivery, unloading, storage supplies, bedding, water treatment, extra labor, manure handling, fence repair, sanitation, equipment rental, and veterinary or farrier support.
Use current local quotes rather than national averages. Hay, bedding, fuel, labor, and hauling prices can vary widely by region and may rise during a disaster. A useful worksheet should show a typical local range for each item, the assumed quantity, and the date the quote was obtained.
For example, record a low and high local quote for a bale, then calculate the total under both scenarios. Confirm whether delivery, stacking, taxes, emergency access, and minimum order requirements are included. Put any boarding price, deposit, refund policy, damage responsibility, and feed substitution terms in writing.
How should a boarding agreement address forage shortages?
The agreement should identify who supplies hay, who approves substitutions, and who pays for emergency purchases. It should also state what happens if the owner's preferred forage becomes unavailable.
Include written instructions for feeding quantities, feeding times, slow-feed equipment, supplements, medications, and dietary restrictions. State whether the facility may change a ration in an emergency and who must be contacted first.
Also address access during evacuation conditions, owner communication, veterinary authorization, emergency transport, liability, damaged equipment, and termination of the arrangement. Avoid vague language such as “reasonable feed.” Define the expected daily amount and the process for documenting changes.
How can you reduce hay waste without underfeeding?
Waste control should protect access to forage, not simply reduce the amount offered. Slow-feed nets, racks, tubs, or protected feeding areas may reduce trampling and scattering when used safely and sized appropriately.
Measure what goes into each feeding area and what remains. Compare the results over several days. A horse that leaves long stems may need a different forage, while a horse that finishes rapidly may need a safer delivery method or a revised ration.
Keep feeding surfaces away from the wettest parts of the paddock. Remove spoiled leftovers, clean equipment, and inspect nets for broken strands or entanglement hazards. Any feeding device should be appropriate for the horses using it.
What water and sanitation issues accompany a hay plan?
Horses need dependable access to clean water, and water service can fail after a storm even when hay is available. Test or assess emergency water sources before relying on them. Flooded tanks, damaged lines, and contaminated wells require local evaluation.
Place hay where it will not fall into water containers. Clean tubs regularly and monitor intake, especially when horses move from pasture to dry hay. A sudden diet change combined with dehydration can increase health risks.
Manure removal also matters. More hay generally means more manure, and wet conditions can make removal difficult. Plan a temporary collection area that does not drain toward wells, streams, or feeding and watering locations. Confirm local environmental and disposal requirements before establishing a long-term manure site.
How do you decide whether to accept more boarders?
Set the limit using the smallest critical resource, not the number of empty stalls. If the property has 20 stalls but only enough usable hay for 12 horses for the planned recovery period, the practical capacity is closer to 12, adjusted for reserve and other constraints.
Capacity can also be limited by turnout, quarantine space, water, labor, trailer access, fencing, medical isolation, and safe manure handling. A storm may make one or more of these resources unavailable.
Create a written intake threshold. For example, accept additional horses only when the property has confirmed forage, safe stalls, clean water, an emergency contact, and a transportation plan. Stop intake when the reserve falls below the chosen threshold.
What should you do if the hay calculation is wrong?
Measure actual use early rather than waiting for the stack to look low. Weigh a sample of bales, count bales issued, record refusals, and compare planned use with actual use. Recalculate after any change in horse numbers, forage type, turnout access, or waste level.
If the supply is falling faster than expected, contact suppliers immediately. Ask about bale weight, forage type, delivery timing, and whether the hay was exposed to weather. Do not make abrupt dietary changes without professional guidance, particularly for horses with a history of colic, laminitis, insulin dysregulation, or other diet-sensitive conditions.
If a horse stops eating, develops diarrhea, shows colic signs, becomes unusually depressed, or has other concerning symptoms, contact a veterinarian promptly. A forage shortage is a management emergency, but it can become a medical emergency as well.
What is the final forage test before opening a storm boarding space?
Use this final test: Can you state the number of horses, the daily usable forage requirement, the number of days covered, the expected waste, the reserve, the storage location, the supplier backup, and the person responsible for checking the numbers?
If any answer is uncertain, delay expansion until it is resolved. Boarding after a storm can help horse owners and protect animals, but good intentions are not a feed plan. Count pounds, not just bales. Count horse-days, not just stalls. Inspect pasture, water, storage, and access. Confirm prices and local requirements before committing.
The safest temporary facility is the one that knows its limits. A conservative forage calculation gives owners clearer expectations, gives horses more reliable care, and gives the property a better chance of recovering without turning one storm into a second emergency.
