I am building a temporary moveable coop since it's time to get the gals out of the brooder and I haven't got the permanent one finished. It is going to have a 2' x 4' x 3' high closed coop and a 4' x 6' run. I have four chicks. Do they need water and food inside the roosting coop if they are closed in at night or is outside enough. or maybe just a water nipple...? Trying to fit everything in!
