The square vs round bale debate comes down to three things: cost per pound of actual hay, your storage and handling setup, and your herd size. Neither format is universally better — the right choice depends on your specific situation. This guide breaks down every variable so you can make the comparison for your farm.
Cost Per Pound: The Only Fair Comparison
Never compare hay by sticker price per bale. A $7 small square bale at 40 lbs costs $17.50 per 100 lbs of hay. A $95 round bale at 1,000 lbs costs $9.50 per 100 lbs. The round bale is nearly half the price per pound of actual hay — before factoring in waste.
| Bale Type | Typical Weight | Typical Price (2025) | Cost per 100 lbs |
|---|---|---|---|
| Small square (2-string) | 40–60 lbs | $6–$14 | $12–$28 |
| Large square (3-string) | 80–120 lbs | $14–$28 | $14–$25 |
| Round bale (4×4) | 400–600 lbs | $40–$80 | $8–$16 |
| Round bale (5×5) | 800–1,100 lbs | $70–$130 | $7–$15 |
| Round bale (5×6) | 1,000–1,500 lbs | $90–$160 | $7–$13 |
Round bales win on raw cost per pound in almost every scenario. The question is whether the additional waste from round bale feeding and the handling equipment required erases that advantage.
Waste: Where the Comparison Gets Complicated
Round bales fed without a proper ring feeder can lose 35–50% to waste — which can more than eliminate the cost-per-pound advantage. Small square bales fed in a manger or rack typically waste 5–10%. The break-even point:
- If you have a good hay ring or feeder (12–15% waste), round bales are almost always cheaper
- If you're feeding round bales on bare ground with no feeder (40%+ waste), square bales may actually be more economical after accounting for waste
- For goats specifically, round bale waste without a proper feeder is so high that small square bales in a keyhole feeder often win on total cost
When Square Bales Make More Sense
- Small herds (1–3 animals). A single horse or a few goats won't finish a round bale before quality degrades in wet weather. Small square bales let you feed precise amounts without spoilage.
- No tractor or loader. Round bales typically weigh 800–1,200 lbs and require a tractor with a front loader or bale spear to move. Square bales can be handled by one person with a hay hook.
- Limited storage space. Square bales stack tightly in a barn and can fit in spaces too small for round bales.
- Rabbits and small animals. Small square bales are the practical format for species that consume very little per day.
- Need for portion control. When feeding horses with metabolic issues where precise hay rationing matters, square bales are easier to measure accurately.
When Round Bales Make More Sense
- Larger herds (5+ animals). A round bale feeds a group continuously, reducing labor vs. daily square bale distribution.
- You have a tractor. Handling round bales is trivial with a front loader or bale spear. Without one, it's very difficult.
- Free-choice feeding is the goal. For horses or cattle with 24/7 hay access, a round bale in a ring feeder is significantly less labor than refreshing square bales multiple times daily.
- Long-term winter storage. Large round bales, properly stored, lose quality more slowly per pound than small square bales in equivalent outdoor storage conditions.
