This is still the first year with my girls, so I'm still learning. My 2 JBG have these bald spots. I do not see any signs at all of mites, and everyone else seems to be fine. I was thinking the one that is balding on her head (it looks redder in the picture than it does in person. it's not raw or anything) might be a pecking order thing (we have a couple mean red stars), but then the neck on the other one went bald. This would be our first molt, so I just wanted to double check that is indeed what it is.
