My friend down the road and I bought a whole set up of coops and hens from a guy who didn't have time for them anymore. There were 39 hens and one goose. We split the hens and I have a coop and 18 hens at my house now and she has the rest down at hers. Of the 39 hens, I would say about 8-10 of them are missing feathers around their tails and back. We tried to split the group evenly, I have about 3 that have been pecked pretty badly. It does appear that there is some new feathers trying to come through the skin. The worst one is a barred rock and the others are RIR's. I have not seen blood or scabs, but the bright red skin is concerning and it just breaks my heart for them. They seem fine other than that, they are laying, eating, scratching and making noise as they run about their yard. I believe that splitting the flock was a good thing for them, as I think he may have had too many in a spot that was too small for 39 hens. But tonight I witnessed one of the RIR pen another one down and bite and peck at the comb of the one she had penned down, it was brutal and hard to see. They have only been at my house since Sunday night so I have yet to let them free range. I would gladly take any suggestions you all might have regarding this situation.
