What about lighting? Do chickens need light in the coop? Now that it is warm a heat source isn't necessary. Are chickens afraid of the dark? Last night with no light on in the coop they wouldn't go in as it got dark. So they ended up lined up on a "deck area" that runs along the front of the coop. It's a shame to have a coop for them where they'd be safe and they won't go in. I thought chickens were instinctively supposed to go in at dusk. Oh, the little darlings are 2 months old.
