I have 8-week old chic's and they have been outside for 2 weeks now. I have had the heat light in the coop for the last two weeks since the temperature drops below 50 at night. Every night for the last 2 weeks we have been putting them in the coop at dawn. The other day they finally figured out to go in the coop themselves when the light turns on at 8pm. Additionally, I have it turning off at 5am when the sun comes up. My question is when we remove the heat bulb in another week is it a good idea to use a very dim supplemental led light inside the coop so they can find their way back inside to the coop and perch?
