If you remember back in the spring I had a calf with a broken leg. After the cast came off in 6 weeks it's hair started coming out. I'd seen calves lose hair in patches before but this one lost most of it's hair. Looked awful. He ate good and felt good though. We had another one start losing large amounts of hair 2 weeks ago. We washed him in 10% bleach solution, let it stay on for 15 minutes and washed him in fresh water. He stopped losing hair and the crusty skin under it cleared up in about 3 days. I hope it will help others with this problem since the vet nor anyone else seemed to know what it was. Thanks Baron
