Can anyone help me with this mystery? I have 2 1/2week old silkie chick who has this mystery bald spot on the side of her crop/neck area about the size of a large marble and its intirely bald. She's happy and healthy though, and its not even noticable till I get her out and handle her. She's the only chick in the group with this and she's also one of the biggest so I dont think she's being picked on but I could be wrong. FYI- Her crop is huge in this pic because she just pigged out on boiled egg lol. Any ideas what this spot could be and if its anything I should concern myself with?
