I have a 4 month old calf that is losing all of her hair, no other cattle are losing hair. She is an orphan that I bottle fed and then I turned her in with the other cattle a couple months ago and all of my cows alow her to nurse from them. I had the vet out and he said it was not a parasite or fleas and that he wasn't quite sure that maybe someone was licking her alot and that's why she is all patchy. Im just curious if anyone has had this issue before. I posted a pic below
