This 4' X 4' X 4'5" box held rolls of carpet at lowes. They gave it to me for FREE. It had this awesome heavy duty wire frame on it to keep the rolls of carpet up. I use flannel-backed tablecloths as washable/reuseable liners (fuzzy side upwards for traction and absorption) so it stays cleaner and the cardboard stays dry. We paid for the heat light though. The waterer and feeder are full size so they move to the coop when the chicks do.
