My daughter just picked up 4 adorable silkie chicks from our local feed store. One of them has really bad pasty butt and the other has a tiny spot on its back and the others are picking at it and making it worse. I have blue kote..Can I put a small dab on her back? And is there anything I can do to make the others pasty butt any better? I'm dabbing aquaphor it around it to soften it and keep her vent open. Any advice would sure be appreciated!
