Hello For our brooder, we used a plastic tub with walls about a 2 feet high. We then in the inside placed cardboard to surround the plastic walls, and corners. We decided to hang the lamp from the ceiling into a corner on the brooder. Should we have any concerns of the plastic melting, cardboard catching on fire, or anything else? The lamp is secured to a hook on the ceiling rather well. Also, what would be a good amount of space per chick? We have 6 chicks in 1 brooder. I figured between 1 and 2 square feet per chick. At the moment, they are about a week old, so. Thanks, anything you can add would be helpful.
