My little bantam polish has a bare spot at the top of her head, I thought it was just filling in weird but the pin feathers are gone and its getting a little calloused or scabbed. So I put Blukote on it. I had never actually seen anyone pick at her till now. They are fascinated and obsessed with it! I separated her and the other polish by putting a box witha grate in the brooder but what can I do now?
