My chicks are 6 weeks old, pretty much fully feathered (still a bit of fluff here and there). Hopefully we will get the coop finished today or Thursday, so I'm looking at moving them out of my family room this weekend. Here's my question- I still have the light on 24 hours a day. They are in a really, really big cardboard box, so without the light it is rather dark in their brooder. When I have tried turning the lamp off in the past, one in particular gets very upset with me and sounds the alarm, peeping at the top of her voice. Also, last time I tried they all ended up on one roost all snuggled together. We have had the coldest April in history here in the Northwest, so our furnace is still running, the house is kept at 68. I don't think they really need the heat from the lamp, I think they are just acting a bit spoiled. Should I be turning it off at night now, to get them used to the idea that night time is dark and the "sun" isn't up all day and all night? Or should I turn it off all the time?
