I hope no one minds me starting my own thread on this topic, I didn't want to high-jack someone else's thread to ask my questions. I have 4 birds (3 pullets & 1 cockerel) that are 12 weeks old. They have been in their outdoor coop/run area for about a month and a half now. I also have a 5 week old pullet RIR. I was not aware--nor did I consider--the need to quarantine from each other but I do know I needed to create a safe introduction, so last Tuesday the younger bird left the brooder and went outside with the other birds, but I've kept her in a dog kennel (see photo below) so they can see each other but not injure the younger chick. So my questions are: how long does the Rhode Island Red pullet need to stay separated from the rest of the flock? How should I go about releasing her into the older flock? Also, the barred rock cockerel likely won't be around for too much longer as I cannot keep roosters where I live, so how will removing him affect the flock dynamic? From what I can tell, he's the top bird and then the buff orpington is next in line in the pecking order, then the Easter Eggers at the bottom of the order.
