Our current situation is that we have two separate flocks in two separate coops with two huge separate runs. The first bunch were raised and it was several months later before we got the others. The first flock were all raised together and there is one roo. They will not let other hens join them without worrying them to death so when we got the others, we just built another coop. The new ones have an adult EE Roo who's very laid back. The original roo is also pretty mellow. I have been alternating allowing each flock to free range. My question is regarding the roosters.....can I let them all out at the same time? Will the roosters fight? Will one end up dead? I love both flocks and during the winter I hate for them not to get out in the yard and which ever flock has to stay in pouts all day! Seriously, if they are still in and we are working outside, they will not be quiet and follow the edge of their fenced run and "fuss" at us. So, someone tell me if you have experience putting more thatn one roo together. Thanks.
