I have a six week old Silkie peep who just started exhibiting some weird motor issues. She can walk around just fine and do all the normal things chicks do, but when she stands and looks at me head on her head falls to the left as if she is having trouble holding it up. It kind of bobs up and down. Is this some sort of neurological issue or indicative of something else? Can it be corrected or will it get worse? She has not suffered any injuries that I am aware of and has been safe in her coop with all the others since I brought her home. Thoughts?
