When can I turn the heat lamp off? My chicks are 6 weeks old tomorrow and they have been sleeping in my basement. They have been acting like they are getting hot. I've raised the lamp about as high as I can and it is about 70 degrees next to their box. Are they ready to be without it? We haven't finished building their coop. It may be another week or two before it's done. I live in cleveland Ohio. So weather here is unpredicable. One day it's 80 the next it's snowing and 20. When should it be ok for them to finally go outside?
