So I had two barred rock hens and a RIR rooster, the three of them had a coop and free ranged together. Today my neighbors dog was running loose and killed one of the hens and a rooster. (I saw the dog on my property with the chicken in his mouth and am planning on talking with my neighbor about it later). Now I have one barred rock hen left. I know that chickens are flock animals and she won't do well living by herself. I have 3 silkies who are about 3 months old living in their own coop and fenced in run. I originally planned on keeping the silkies separate, but due to the circumstances would it be ok to let the hen live with the 3 month old silkies? I don't want her to pick on the silkies and I don't want to buy anymore chickens until I build a larger secure run for them and speak to my neighbor about their dog.
