DW, (OkieQueenBee) has two 250 watt bulbs in there and they still pile up on each other. We had to raise them a bit when we saw a couple of them smoking
I have added more roosting space and sealed up some of the drafts but at twelve weeks I thought that they would be feathered up well enough to take some cold. I guess not. I will look into the Brinsea brooder, thanks.
