Peacock Feathers Broken

[Frizzled]

I have a 2.5 or 3 year old peacock who's tail feathers are broken off and just look bad. He has a huge run so he has plenty of room to move about, any ideas why this is happening? Does he need a different kind of food? I am giving him corn and he eats layer food with my bantam chickens. Thanks for any advice in advance.

When was he last wormed or checked for lice/mites? I had a 3 year old male peacock pull out/ break off his feathers because of this.

Its been awhile, I'll check and worm him. I very seldom see him messing with his feathers though.
