Question: how many square bales of hay per horse?
Answer: From October 15 to May 15 the horse would consume about 4,280 pounds of hay or 2.1 tons. This would equal 86 fifty pound small square‐bales or five 900 pound round‐bales during this time. For two horses, this amount would be doubled; 172 small‐square bales or 10 round‐bales.
