We have a JG Blue Rooster who is about 10 months old. He seems to be having some sort of an issue on his neck/throat. The feathers almost look sort of soft and thinning and he has what looks like a couple sores. Is he moulting at this age maybe? He does a sort of move with his neck that reminds me of that '80s dance move that Paula Abdul and Janice Jackson did, remember that? Also noticed this morning he isn't getting a complete crow out, sort of stops in the middle. Behavior otherwise seems normal. None other of the flock is behaving this way. No other roosters in this flock. He is considerably larger and taller than all the other hens.
