I probably SHOULD know the answer to this question BUT!!! Anyway here goes, "What is equalivant on amount of hay in square bails vs round bails! Well I know that sizes vary but I'm looking for a general rule of thumb, how many square bails = 1 round bail? The reason is have another boarder that borrows/steals hay all year and once a year hauls in a round bail(questionable quality) and considers it equal! She's family to owners and when it comes to me or her I know who is leaving and I'm lucky she's down to one horse!
