This is my first peacock to own, and I'm a little concerned. I've researched, but can't find any answers as to why my male peacock won't grow his crown on top of his head??? Also, I know they lose their tail feathers, but my man hasn't grown any and I have had him for about 6-7 months now. I'm not sure how old he is, pretty young I'm guessing, but just about full grown. I picture is attached. Does anyone have any helpful advice ???
