I'd like to, but everyone is free range and I can't let the chicks range yet or my cats will eat them. But I can't close the door to the coop and not let the adults move in and out. The kennel is so large it won't fit in the coop.
I'm needing to do the same thing. I have a free range hen that hatched out chicks (we have no idea where) and I will need to integrate her and her chicks back into her original flock. So you think 5 weeks is safe? I have them in a kennel for now so my cats don't eat them.
