Why a DIY Horse Hay Feeder Makes Sense
Whether you manage a multi-horse boarding facility or a single backyard companion, hay waste adds up fast. Extension studies such as the University of Minnesota’s “On-Farm Hay Waste” trials have shown uncovered ground feeding can sacrifice 20–30 % of every bale. Repurposing affordable materials into a dedicated feeder routinely cuts waste in half, lengthens feeding time, and supports a healthier digestive rhythm. After experimenting with several prototypes over three winters in our Mid-Atlantic barn, the following plans balance practicality, budget, and horse safety.
Benefits You’ll Notice Immediately
- Less hay on the ground means lower feed bills and reduced manure clean-up.
- Slow-feed designs mimic grazing, helping stabilize gut pH and curb boredom-related vices.
- Strategic elevation keeps forage free of mud and manure, reducing respiratory irritants such as mold spores.
Planning Your Design
Before grabbing a saw, measure the following:
Number and size of horses. A 1,200 lb gelding pulls hay differently than a 700 lb pony. Allow at least one feeding station per dominant horse to avoid resource guarding.
Typical hay type. Leafy second-cut timothy packs tighter than coarse orchard grass. Tighter hay benefits from a wider grid or mesh hole to prevent frustration.
Location. Outdoor feeders should sit on well-drained gravel or geotextile fabric. Indoors, ensure at least a four-foot clearance around all sides for safe withdrawal by subordinate herd mates.
Choosing Safe, Durable Materials
Weather-exposed lumber needs rot resistance. We have had excellent luck with pressure-treated lumber and naturally rot-resistant cedar boards. Avoid chemically treated pallets that bear the “MB” (methyl bromide) stamp; look for “HT” (heat treated) instead. For fasteners, choose exterior-grade deck screws or, better yet, coated lag bolts rated for livestock applications.
Step-By-Step Build: The Pallet V-Feeder
The pallet V is popular because nearly every farm already owns the bulk of its parts. Two sturdy, matching pallets are hinged together at one long edge, forming a collapsible V shape that funnels hay toward the bottom while allowing your horse to eat through the top.
Tools and Supplies
- 2 heat-treated pallets (approx. 48″ × 40″)
- 4 heavy-duty door hinges
- 3″ exterior screws and washers
- Optional: ¾” plywood square to cap the bottom point
Construction
1. Lay pallets flat, long sides touching. Screw hinges along that seam. When you stand them up, they form a self-supporting V.
2. Cap the bottom with plywood so hay cannot wick moisture from the ground.
3. Sand any splinters and countersink all fasteners. Horses love to itch noses on edges; a protruding screw is a guaranteed vet call.
4. For a slow-feed upgrade, drape a slow feeder hay net inside the V and secure the top corners to the pallet slats with carabiners. This limits the mouthful size without forcing you to reload multiple small nets every day.
Alternative Slow-Feed Concepts
Looking for something more refined or better suited to stall corners? Here are two field-tested designs we’ve built and monitored for over 18 months:
Box Feeder with Wooden Grid
A 3′ × 3′ × 2′ deep box, framed from 2 × 4s and sheathed in 1″ boards, holds roughly half a small-square bale. Over the top sits a removable frame crisscrossed with 1½” oak slats spaced 2½” apart, creating grazing-sized gaps. We borrowed the spacing concept from slow-feed plastic grates on the market but wanted sturdier wood that could endure occasional pawing. The whole lid lifts for rapid morning chores.
Net-in-Frame Feeder
Suspending a heavy-duty hay net inside a rigid frame keeps the net from collapsing on itself as the volume drops. We welded a 3′ cube from scrap steel tubing, then hooked a large-capacity extra-large hay net across the top rail. Horses tug hay through 1¾” holes, which extended consumption time on a 20 lb flake from 1 hour to almost 4 hours in our stopwatch test.

Safety Checks and Maintenance Routine
Any equine equipment becomes a hazard if ignored. Put a recurring reminder in your phone to inspect your feeder weekly:
Fastener integrity. Loose screws migrate outwards with vibration. Re-tighten or replace immediately.
Surface wear. Splinters appear as wood swells and contracts. Quick sandpaper touch-ups prevent gum lacerations.
Drainage. Remove rain-soaked hay daily. Studies published by the EQUUS Foundation highlight that mold can develop within 48 hours in humid climates, increasing colic risk.
Seasonal deep clean. Every quarter, power-wash or scrub with a mild, horse-safe disinfectant. Allow all wood to dry completely before refilling.
Placement Tips for Maximum Waste Reduction
• Situate the feeder on a packed stone base or old rubber mats to discourage rooting and mud.
• Face the open side away from prevailing winds; dry hay blowing across a paddock defeats the whole purpose.
• Provide at least 18 inches between parallel feeders so shy horses have an escape route.
Real-World Results: What the Numbers Show
Last winter our four-horse herd averaged 120 lb of hay per day when fed loose on the ground. Using the pallet V with a net upgrade, we recorded an average collection of only 10 lb of trampled waste per day—an immediate 58 lb saving. At $280 per ton delivered, that equated to roughly $240 in monthly savings, paying for all materials inside of two weeks.
Behaviorally, we noticed:
• Fewer cribbing episodes by our senior Thoroughbred.
• Reduced pacing at the gate during evening turnout transitions.
• Even weight distribution heading into spring, with no horses presenting the ribby or cresty extremes we battled in previous years.
Frequently Asked Questions
Will my horse damage his teeth on wooden grids?
Dentists we consulted report minimal risk provided wood edges are rounded. Steel mesh, by contrast, can accelerate incisor wear when hole diameters are smaller than 1½”.
Can I use PVC pipe instead of wood?
PVC becomes brittle in sub-freezing temperatures and shears into sharp shards under hoof impact. Stick to structural lumber or metal.
Is the pallet V safe for shod horses?
Yes, if you recess all nails and reinforce corners with angle iron to prevent splitting. We have not observed shoe catches in over two years of daily use.
Final Thoughts
Tack shops stock dozens of commercial feeders, yet many rely on the same core principles you can implement for a fraction of the cost. By selecting horse-friendly materials, integrating slow-feed elements, and committing to regular maintenance, your DIY hay feeder becomes more than a money-saving project—it becomes a cornerstone of responsible horse stewardship.
