A question presented to me:
Who would be liable if a boarded horse ended up with fox tails in its mouth from eating hay with fox tails?
Additional information: horse is boarded and was getting alfalfa mix round bales, but barn ran out so switched to grass bales, and this grass bale contained the fox tail. The barn bales their own hay. Two horses are affected: one seems ok after obvious fox tail removed, but other still fussing and will likely need a vet.
Barn removed the bale and is now forking hay off it into the pen.
