Due to unforeseen circumstances, my new flock of five just became two. (3 out five were roos ). I have two 12 week old barred rock. I've just added two EE and a red sex link. They are about 5 weeks old. Currently I have a small run for the new girls, within the main run and I have the coop separated with chicken wire. They are together yet separate 24/7. My question is this: How long should this process of separation continue before I can start letting them be together? Any thoughts or opinions are greatly appreciated.
