I have a small flock (9) of mixed breed girls that are about 18-19 weeks old. I am trying to integrate 3 10-11 week old chocolate orphinton pullets. Things are not going well at all. I am currently building a new coop and run which will be much bigger. I was thinking that when it is finished I could put the younger girls in it first for a day or two and then bring the others in a few each day until everyone is living together. I am hoping this system will make integration easier. Any thoughts or has anyone tried this?
