Great advice and directions. 2 things that worked well for me - (1st) I got 2 coop heating pads, one for under and one on top of the mommy cave. Some of the chicks preferred to sit on top. (2nd) I had my brooder pen made of 4 2x2-framed chicken wire "walls", that were held together with 2 hooks and eyes on each side. That way, after brooding season, I could just unhook it and put it back out of the way in the pen.
