Regrowing bald spots?

[Year of the Rooster]

One of my sebrights pullets has been badly overmated by my stupid silkie roosters

and currently has a large bald spot on her head. I rehomed some but I guess I was too late. Is there anyway I can get the feathers to regrow? If not, why? Did the roos pull out the follicles or something?

yes the feather folicles can be pulled clear out of the chickens head
she may never get all of her feathers back
she will need lots of time allone and not bothered by roosters
she can use some high protein feed and calcium to regrow new feathers
at best it will be from 6-8 weeks before you have feathers in the area
silkie roosters are tooo big for sebright hens
