Hi, I have 7 chickens and one rooster. They have been in a smaller coop since june, but now my hubby made a larger one with a light and its much nicer and bigger. (we can actually walk into it). How do we get them to go into the new coop? The girls lay thier eggs in there in the day, and free range after that. Should we close up the old coop, and if we do that will they go roost in the trees? I'm afraid of coyotes getting them. thank you for your help!!!
