Thanks again! I do know that wet hay is ok to feed horses, as Bruno had a dry cough for a few days and the vet told me to wet his hay and see if that helped, which it seemed to. He had no issues eating the wet hay, didn't seem to bother him or deter him at all. He gobbled it right up!
I was just worried about the wet hay sitting and getting moldy, especially in hot and humid SoFla. I separated the flakes on my patio and dried them in the sun. Flipped them over, dried them some more. Of course I couldn't put the bale back together, so my feed room is kind of a mess now! :) I keep the hay on a pallet so it can get air, but I also cover it loosely with a tarp because I know if an animal pees on it, it can be really bad for the horses.
Love learning stuff on this forum! Thanks!
