Rooster loosing neck feathers and comb frost bite hens not loosing feathers

[Finnegan]

Speckled Sussix rooster loosing neck feathers. Hens are fine. Rooster has some comb
frostbite. Sleeping in one of the nest boxes. Should he be separated from the hens.
He also had a limp last week. That seems better. Hens are acting normal and on their roost.

Welcome to BYC. Could your rooster be starting to molt, or have his feathers picked by the hens? Does he have any frostbite on his toes or foot with the limp. If he is still limping, I would place him in a crate inside the coop with food, water, and vitamins,for at least a week to let him rest the leg, and re-evaluate him on a weekly basis. His frostbite on the comb should be treated with Neosporin ointment--not rubbed in or massaged, but just dabbed on.
