Hi, I am trying to integrate two new pullets to replace two lost to hawks. I have an easter egger and a black australorp who are about 9 months old. I got a barred rock and a new hampshire red , both about 5.5 months. I housed them separate for a week but let them see each other. Now due to other circumstances they have to be together. I have combined them in my larger coop and run. Coop is 6 by 4, run 4 by 14 ft so they have lots of room. I know they have to establish pecking order but it is making me nervous! The easter egger ( who of course was the bottom bird in the past) is being super aggressive to the new hampshire red. She attacks her and pecks her, but the younger bird can typically get away. She has been cornered in an egg box however. No blood is drawn but wow is that easter egger a meany! I am assuming I just need to let this work itself out, it has only been two days and three nights. All is quiet at night and all are in coop. I go out if I hear alot of bickering and break them up, but maybe I should not even do that? I feel bad for the new hampshire, she is pretty scared. I do see her and the barred rock eating and drinking when the older two are in the coop so I know shes not starving. Should I do anything else?? Thanks!
