Hello All! I have 8 young (born in December) chickens out in the coop and run. Yesterday I bought 6 chicks, supposedly all pullets but we'll see. At what age should I introduce them to the rest of the flock outside? Any tips on how to introduce them? Outside I definitely have 1 cockerel and 6 pullets. The other 2 are still under question! None or yet laying eggs. I only have 1 coop. When they go out, do I have have to keep them separated? Will the others hurt them? I never introduced other chickens into established flocks before so I need advice. Thanks!
