One of my young birds (six weeks old) has a partially bare patch on her neck. I don't know why. Is it mites? cannibalism? Is it normal? How concerned should I be? None of her siblings have this problem.
(These chicks have several different breeds in them. Their mother is silkie/ameraucana, and their father is unknown.)
They don't like getting their picture taken so the images are not the best, sorry.
