We have 14 mixed breed 10 week old girls (maybe one roo). We introduced them to their new run 2 days ago. Is it normal for mom (me) to have to show them how to get back to the coop when it's dark thirty? They do have access to underneath the coop and love under there. We may have to close this off to them. I'm not ready to leave them out of the coop. Besides my husband worked very hard on the coop, they need to enjoy it. Any suggestions?
