In the brooder, the chickens had light 24 hrs. The first few nights out in the coop, I left the light on. But, for the past two days and nights, I haven't been giving them light at all, just natural sunlight. I don't want to have to leave the light on all night long. Well...they are not liking it. They settle down when it's dark but until then, they are in a ruckus! I feel bad, but it's like tough love, ya know? So, do you have a light on and if so for how many hours?
