I just bought a 2 yr old fainting goat that has patches of hair falling out with crusty skin atattched. I believe I remember having a rabbit with a fungal infection that looked like that. She also has a small round patch of hair missing on her hip and thin hair above her nose. How can I treat her? I have pour on ivermectin and tea tree oil on hand. Can get something else if need be. PLEASE! I would really appreciate any advice as I am very new to goat ownership.
