I have just introduced 6 new 12 week old hen's into my established 1 1/2 year old hen's coop and yard. She is of course establishing the "pecking" order (literally) and has become quite vocal and animated around her new family. She tends to sit on her nest much more and has not had her laying affected. I kept the chicks in an adjacent yard with a fence between them for about a week before I opened the gate and put them together. Any suggestions on whether this was the right way to do it ??? I do not have a rooster in the mix. I really don't need a chicken in therapy !!
