OK. So, here I am again, trying to introduce some 8 week old pullets to my 16 week old mixed flock and one 10 week old bantam. One is docile and doesn't care. All others (pullets) just chase the new ones around and peck at the back of the new girls' necks. Is this just a rite of passage and how long can this go on? I have had to separate them...now into three different areas. I have four in the coop, and have the 3 newer, but older hens that I am trying to somehow introduce to the flock in one side of the run, which I have divided into two. The two newer pullets are now with the more docile EE and little bantam (which has some little nasty pecking habits picked up from her elders, I am sure) in the other side of the run. Is there a chance that they can ever be one big, happy family?
