Have seven week old chicks that have never known darkness since they have been in a brooder with heat lamp - put them in Coop with lamp almost two weeks ago. I live in New England so it is still cold at night 30-40. For that matter - Really has been much warmer in day!! We had one warm night that I didn't need the lamp. So I shut it off. They went nuts - they slept near the trap door in the run. When I put a light on they came inside - I experimented with light on and off - they had reaction every time. What do I do? Can they see the water and food in the dark?
