I have a one year old Boer cross doe that i just picked up last week. Today I noticed that around both ears the hair is gone. Her eyelids are red. I gave her a copper bolus tonight because her coat is kind of rough. She has free choice minerals, hay, and mixed grain once a day. Not sure what her diet was at the last place. Any suggestions on what this could be? Her skin where the hair is missing is smooth, no scaly patches.
