any time you change up the flock there is going to be upheaval. Maybe you can try doing it at night? Otherwise, I think they just have to work it out amongst themselves.Alright, I have a new problem that I didn't find addressed here and it is a different problem than most that incubate hatch face. I have two brahma chicks that were raised under a broody in a mixed flock. I'm separating the brahmas into a different breeding pen so that I can keep their lines pure. It has really caused a commotion with the entire flock, both sides. Does anyone have an easy way to do this so that it doesn't cause so much havoc?
