Hello- So I am having a bit of a problem. I have my hens and roosters together that were raised from day old chicks last February. I have some juvenile pullets that I am attempting to introduce to the flock, and each time I introduce one it is killed. I sat and watched them for a while, the rooster was being somewhat protective of the pullets, while the hens went to their 'pecking'. When I walked away to do something else, I heard a lot of commotion only to see several hens ganging up on the pullet and she is gone before I can get in to retrieve her. The flock has never been this way with any other animal- ducks, goats, our dogs even. But, I need to find someway to get them to get along- any suggestions? The current flock consists of red rangers, a buff, an Ameraucana, and a few sex links.
