Hi, I am new to this forum and raising chickens. I had 5 Columbia Rocks, 4 hens and 1 rooster. Recently, I lost 3 of the hens and the rooster to foxes. I have one hen left. I would like to purchase more Columbia Rocks. Does anyone know a breeder who sells this breed of chicken? I live in PA. The family I received the chickens from no longer have Columbia Rocks. Also, what (if anything) can I do to protect the lone chicken I have left (besides keeping it in an enlosed area). Once foxes know there are chickens, will they keep coming back? My chickens are free ranging. I look forward to your responses and being a part of this community of chicken lovers!
