My grey is 18 yrs and has had no problem. About 1.5 weeks ago he started plucking (all the light grey/white feathers are gone and looks like a walking plucked chicken with dark grey wings). The consences is that he is going through puberty and is a bit backed up since he doesn't have a mate. Is there anything to do to relieve this situation or to get over the issue? Will this pass? Teenage boys were bad enough, but I never thought I would have to go through this wi a bird!!!
