I have seven chickens. One is a white leg horn, I don't remember what the others are. Is culling important , if so why, and how is it done. I was hoping to keep my chicks forever. They are five weeks old now, I live in Riverside California and I am getting ready to put them in their coop, Can a hawlk or an owl steal or kill a chicken? Are they ever save from them if one can. We also have gofers. I have a million questions but I will get these answered first.
