A few months back I bought a bale of hay for my horse. A few nights later it heavily rained. Days later I went to put my horse away and I grabbed some hay but it was completely moldy, all over ( I put the hay in the stable when I bought it) Turns out there's a leak in the roof.
Anyway, I decided not to waste it so I spread it on the floor of the chicken/duck cage for them to lay on. But my horse somehow got into the cage and started eating the moldy hay ( I don't know for how long she was doing it before I found her and stopped her).
I'm quite worried, will she get sick from the hay?
( Also the days in between the rain and putting her back in the stable I hadn't fed her the hay yet, so she didn't eat the moldy hay then, just now)
