Hi everyone! I’m looking for some advice. I’ve had chickens for a little over four years but this is the first time I’m adding to my flock. We have two chickens that have been around for four years and we recently added six more and two ducks. We’ve been keeping the new flock separated within the run for a week now and today I let everyone mingle for the first time just to see where we were at. Our oldest ISA Brown hen (Big Red) was super nasty, she would run and peck the new girls. I know some pecking is normal so I just let them go at first. I finally separated them again when she went after the ducks. She chased them all around the run and would rip feathers out if she caught them. Our other older hen would peck here and there but it was clearly normal pecking rather than aggression. I know it sometimes takes several weeks to integrate new hens into your flock but I’m just looking for any suggestions from anyone who has more experience doing it. Am I just being impatient and an over reactive chicken mama or should I be concerned that Big Red is going to be a trouble maker?
