one of my aracuana x has some feather damage on her back. the feathers are getting thin and her skin is starting to show a bit, no bleeding yet, but i'm keeping an eye on her. i'm thinking that my roo may be the cause of this but not sure, none of the others have this issue. lately i've noticed hes been getting aggressive w/ the hens again and his spurs are getting a bit bigger. other than the feather loss shes a very healthy hen and good eater/forager too. is it time to get her a chicken vest to protect her? any ideas/help would be great. thanks jim
