I have two free-ranging flocks that I am trying to integrate. I'm new to chickens, so I don't really know their flock behaviors. I have 8 EEs (4 roos, 4 hens) and 14 Golden Comet/Production reds (1 roo, 13 hens). The EEs are 12 wks, the Goldens are 10 wks. So far two EE roos have been, to me, a bit rough with the Golden hens, biting their necks and pulling out feathers. How much of this is okay? As soon as this happens I seperate the flocks because I worry for my hens. Do I let them just work it out, or am I at risk of them killing one another? I also have them housed seperately. I don't have a way for them to meet through a screen either . Well thanks for any input.
