We are just getting over a cold snap, highs in the low 30s,so I wanted to wait to put the 8 week old chicks out. We are still having nights in the 20s, daytime highs 40s-50s. Should I put a heat lamp in with them when I put them out? They have been in my basement that is not heated unless I have the wood stove going. I guess its in the high 50s down there. I have had a 100w light on them, and they do still sleep under it. Maybe put a heat lamp on them for a week or so? I plan on putting them out this weekend, Sat will be about 48 with snow? and Sun. about 50. This is my 1st time doing winter chicks. I might have to rethink doing this again.
