I have 5 pullets in a pen, one of my pullets (jezabell) is mean to the two EE's. Jezebell is a brown leg horn and is 6 months old. My new EE's will be a year in July. I have the EE's in a small chicken tractor, for two days now. Jezebell wont stop picking on them. She is the older of the other 4. I let the EE's out a few times today and she jumps on their backs and stalks them. I am afraid that she will hurt them, even though they are bigger then Jezabell. I wont let them out of their tractor unless i'm there. How much pecking is to much, and should I wait the entire two to three weeks of them staring at each other through their cage. Jezebell is a nice chik, but to be honest she is a grump, that is if a chicken can be a grump, She is the bully of the bunch.
