I just got this hen and the guy that had her, the other chickens beat up on her what can I do? Can i put anything on it? Its a mess will the feathers ever grow back? She is a silky.
You need to keep her isolated for now... clean up her backside and apply honey... her feathers will grow back in time!
Silkie chickens are normally very passive amongst a flock.... once she is in a better condition I would suggest that you introduce her slowly to any other chickens you have.
Honey has natural antibacterial properties, it will soothe her sore backside and helps healing... it contains hydrogen peroxide ( a known antibacterial agent )
