Would anyone happen to know if 5-6 week old chicks still need a heat lamp? I had put them outside in the big coop brooder...but the temps dropped to the single digits last night. Even though they seemed to have survived ok, I was afraid to chance keeping them out there any longer. They are not completely feathered and I didnt think one little heat lamp was enough to keep them all warm. I brought them in the house and its warm in here, so I thought maybe they would be ok without one. Think I will either have to keep them in here til they feather out more and get a bit bigger, or til the temps are consistently warmer. These are ones from my first semi-successful hatch, so I am not willing to take a chance losing them, if I can avoid it.
