First time having baby chicks. I have 12 seven week old chicks that have been living alongside my 6 adult hens for 4 weeks separated by some chicken wire. Is it okay to move them into the big coop soon? Also, all my hens free range around our property. I have put the chicks outside the last couple of days in my kids' playhouse, but they have never been allowed to run around freely. If I move them into the big coop, do I allow them to go outside and range freely with the older hens or do I wait until they are a little older? I just keep seeing images of me trying to chase 12 seven week old chicks in the evening to get them in the coop...and losing lol
