My sweet Golden Comets are a little over 5 1/2 weeks old. In the next day or two the girls will be moved to the big coop when we are finished with the final touches. They are getting way to big and active to be in the bin in our spare bathroom LOL. Here's the thing I keep the light on in the bathroom at all times (son is scared of the dark) and because of the chicks. By the time they get to the coop they'll be 6 weeks if not close. Do we need to have a light at night for them? Or for how long? Once we move our 2 one year old hens we don't light up coop cause they are already trained when to come in. Sorry for long post.
