On Tuesday, we had to put our pet rooster down. We have two hens. Before he died, the rooster was pretty good "friends" with our small Polish Bantam. Those two got along well with our 1-year old Easter Egger. Since our rooster has been put down, the Easter Egger is bullying the little Bantam, who happens to be about three months older than the Easter Egger. She jumps on her and pecks at her while she's on top of her. It's very hard to watch. What can we do? Our Easter Egger and our Polish Bantam are very affectionate towards us, the humans, so we don't want to ruin that relationship. However, the Easter Egger is acting much too aggressive towards the Bantam to not warrant some form of discipline. help!
