I have two or three like the saddle chick. One has no feathers from the wings back and the tummy up and is well like she is sun burned! and this was in the dead of winter, in the coop! the others have got some feathers gone, red skin and some have red butts and no feathers.

I just can't get over the sun burned looking skin!

Once when I was out side one of the roos ( I have two of them, and 18 hens)was walking by and grabbed at a chicken and got the back of her head, but did not pull any feathers out.
