You know if I didn't raise and process my own meat birds I wouldn't have been able to do it. The other day I to remove one of my roosters from the run. Since I mixed the birds last week he has picked on different birds very serverly. He is a 5 month old partidge Rock and the hens are an easter egger who was a little bigger could hold her own and a Silver spangled hamburg which are smaller (but fast) and he just picked on them something awe-ful. So I separated him gave him 3 day to cool off put him back he was OK for while went back the hamburg had no feathers left on the back of her head and a few blood spots and he was chasing her around the coop and run. that was it for me. Too bad he was turning out to be a beautiful bird. I guess sometimes you get an agressive one that is just too rough on the hens. I still have the Rhode Island red, he is very gentle with the hens and has a great disposition with people as well. There seems to be much less tension with the whole flock since he (his name was Jim) was taken away. Its never an easy thing to do.
