I am very new to chickens, I am wanting to start my own flock of about 20-30 birds. i have a huge chicken house that has housed 30+ chickens before, and an enclosed run they can go in, they wont be free range birds.I live in the Texas panhandle so temperatures can get in the triple digits in the summertime and get in the single digits in the wintertime. I'm leaning towards getting black australorps and barred rocks because of their hardiness and the fact that they are dual purpose birds (I am open to other breed suggestions though!) but I'm afraid to raise different breeds together because of what my father in law told me about his birds, he got both brown or red leghorns and another breed that was white, and the leghorns pecked all the white birds to death! So I don't know what to think! Any help/suggestions would be greatly appreciated!
