I have 8 incubator chicks that were born Thanksgiving day. I guess that would make them, six weeks old?? I forget what date Thanksgiving was this year, and my husband threw out all of last years calanders! Anyway, they are fully feathered OEGB chicks and they haven't had a heat lamp on them in about two weeks. They're in my 65 degree basement in a huge plastic tote. Can I put them in the coop with a heat lamp now?
