I have several chicks in three different brooder pens. They are between the ages of 2-5 weeks old. Are of different sizes as well. Mostly larger breeds but I do have 2 bantums. At what age can I move my little ones into the coop with the mature hens? My brooders are full and I have eggs in the bator that should be hatching anytime. I will need a place for them. Are my 5 week old chicks old enough to be moved in with the mature hens or should I put my new turkey babies in with the 2 week old chicks?
