So, I just bought 21 Red Star pullets plus a nice looking young Buff Orpington rooster and pullet from a guy who is moving and selling off all of his poultry, and other animals. I thought this was a great deal (at $2 a pullet) as I was looking to start replacing my current flock of layers soon. The problem is that when I went to pick up the chickens to load them up, I realized that they had been kept in really nasty conditions. They were being fed horse feed, and were crowded into a very small coop with about 80 or more chickens. The floor of the coop was 6 inches or more of swampy muck. I have moved them into a horse stall in my barn and they have their own run separate from (but right next to) to my other chickens. These new chickens smell TERRIBLE and some of them have some really nasty matted feathers, but otherwise they seem healthy and seem to be enjoying their new much more spacious home. Should I be worried? I don't want to contaminate my flock. I guess it is too late one way or another, but I thought I would ask for any suggestions or things to look out for with the new birds. I am hoping that with space and good food they will come around, and maybe even lose the awful smell! Thanks for any suggestions!
