I bought 8 from TSC straight runs. 3 have turned out to be roo's. I got 3 more pullets that are a few weeks younger. The original group get along great. I have integrated the younger girls, but the boys are being quite mean and won't stop pecking them. I have pulled the boys out into a dog crate. I assume I need a new coop for the boys? Chicken math got us, wasn't planning so many and now need to build a bigger run for the 8 hens. Is it typical for boys not to welcome new girls to the flock?
