Something is wrong with my button quail!

Something is wrong with my dear Chickapee's head. Please diagnose this strange occurence if you have any knowledge of keeping gamebirds as pets. Chickapee lives with two other button quails- Tic and Tac (born together). He/she is twice as old as them. Also, can you please tell me if it is a boy or a girl? How do I fix this problem?

I'm not too keen on birds, but have you tried Googling the problem?

Yes. They claim it's fro plucking, but for the months I've had these quails, none have fought or plucked or hit the top of the cage.

That's really weird! If you're really worried, you might find better help asking a vet.
