Barn stocked with fresh, high-quality hay is the cornerstone of successful equine care—but hay storage comes with unique challenges, from fire risks to moisture damage and wasted feed. At Hopehorse Equine, we understand that protecting your hay investment and ensuring your horses’ safety go hand in hand. Follow these proven strategies to store hay safely, maximize your available space, and keep your hay in peak condition for your equine partners.
Hay is highly flammable, especially when baled with excess moisture. Damp hay generates heat as it decomposes, which can lead to spontaneous combustion—a devastating risk for any barn.
For optimal safety, store hay in a separate, dedicated building away from your main horse barn. While constructing a standalone hay shelter requires an initial investment, it is a critical step in preventing barn fires and protecting your horses.
If a separate building isn’t feasible, outdoor storage is an alternative. Follow these best practices for outdoor hay stacking:
Elevate hay bales on pallets to keep them off the damp ground
Cover the stack with a heavy-duty tarp to shield it from rain and snow, while leaving the sides uncovered to allow air circulation
Moisture is the enemy of hay—it causes mold growth, nutrient loss, and heat buildup. Properly prepping your storage space before hay delivery is key to keeping bales dry and intact.
Use pallets for elevation: Place pallets across the entire storage floor to lift hay off the ground, preventing contact with damp soil or concrete that can wick moisture into bales.
Add a moisture barrier: Lay tarps underneath the pallets to create an extra layer of protection against ground moisture.
Prevent wall and ceiling condensation: Ensure hay bales do not touch surrounding walls, where condensation often collects. For metal-roofed storage buildings, attach plastic sheeting to the ceiling to catch dripping condensation before it reaches the hay.
Not all hay is safe to store—bales that are too damp can turn into a fire and health hazard in days. Take the time to inspect every hay delivery thoroughly before stacking it.
Do a manual check: Break open a few bales and feel the interior. If the hay feels damp, clumpy, or unusually warm to the touch, do not store it in your barn. Damp hay will mold quickly, and feeding moldy hay to horses can cause serious health issues like colic or heaves.
Check internal temperatures with a probe: Use a commercial hay thermometer to test the core temperature of bales (insert the probe into the center of a bale and leave it for 10–15 minutes). Follow these guidelines from the University of Minnesota Extension to assess fire risk:
Below 130°F: Minimal fire risk
130–140°F: Low risk, but monitor temperatures regularly
150°F: Moderate risk—check temperatures daily
175–190°F: Imminent fire danger—contact the fire department immediately
Above 190°F: Extreme caution—moving bales can trigger combustion
Poorly stacked hay traps heat and moisture, leading to spoilage. The right stacking method improves air circulation, reduces heat buildup, and allows you to fit more hay in your storage area.
Use the alternating layer method: Stack the bottom layer with cut ends facing up and twine facing sideways. Rotate the next layer so cut ends face sideways and twine faces up. Repeat this pattern for all subsequent layers to create air channels throughout the stack.
Limit stack height: Shorter stacks promote better ventilation and reduce heat accumulation. They also make it easier to access hay for feeding without disturbing the entire pile.
Add a moisture-absorbing hack: Sprinkle rock salt between layers to absorb residual moisture and prevent mold growth.
Proper rotation and feeding practices ensure you use older hay first and avoid feeding moldy or spoiled hay to your horses.
Practice first-in, first-out (FIFO): Position hay stacks so the oldest bales are closest to the storage entrance. This makes it easy to grab and feed older hay first, reducing waste from expired stock.
Inspect bales before feeding: Always pull apart flakes before feeding. Mold often hides deep inside bales, and overlooking it can put your horses’ health at risk. If you find a moldy bale, remove it from the storage area immediately to prevent cross-contamination and reduce fire risk.
Recheck temperatures if mold is found: Discovering mold is a sign that hay may be overheating—use your thermometer to test other bales in the same stack.
A well-organized storage area is useless if you can’t access it during winter storms or busy feeding schedules.
Create a winter snow removal plan: Clear snow and ice from storage area walkways and entry points regularly to ensure delivery vehicles can reach the space and doors can open easily.
Upgrade entry doors: Replace old, stuck, or ill-fitting doors with durable, properly sealing options to protect hay from snow, rain, and wind.
Clean regularly: Before each new delivery, wear a mask and sweep out old hay dust and debris. A clean space reduces mold spores and pest infestations.
Proper hay storage is an investment in your horses’ health and the longevity of your barn. By following these guidelines, you can maximize your storage space, minimize waste, and keep your hay safe from fire and moisture damage.
