I have two 7.5 week old EE chicks and two one-year old PRs. I have the chicks in a coop within a coop set up now and let them out to wander around when I'm outside or where I can hear them call for help if the PRs start going after them (which they do). I have tried putting them in the coop with the big girls at night and that's definitely not going to work - the big girls don't like sharing and the chicks were literally huddling against me trying to get away. What have people found the best way to be to integrate them? Wait till the chicks are bigger and can fight back? I don't want to put them in the coop when it's dark because I won't wake up if the big girls start attacking the little ones in the morning. I was thinking of maybe one night taking the big girls away and kenneling them overnight in the garage and letting the chicks have the coop and then putting the big girls back the next night. Has anyone tried this? The coop is really only big enough for 4 or 5 hens so they'd better learn to get along since I can't section off a chick area.
