I just recently moved my chicks outside to their coop and run. They are only 3 week old bantams, but seem to be doing quite well. I have to put them to bed at night but they get themselves up and out of the coop in the morning. My parents think I am being too mean, though, by not having a heat lamp on at night for them. They really are doing fine, I think; there's 19 of them and when they are all cuddled together (which is how they still sleep), they warm each other up quite well. We live in Michigan and it has been getting colder and the grass is wet in the morning, but I would rather they got used to the weather as it's only going to get colder. Am I being mean by not giving them a heat lamp at night?
