I have about 10 barred-rock and 10 black austrolp hens. I would like to replace my flock with our own eggs. I dont care about pure breeds, I just want calm, even tempered hens. I have had 3 different barred-rock roos (by the hatchery's mistake each time) and they have all turned mean. My children run in terror, I have to carry a bat-no fun.
