I've decided to revamp the system. Instead of the three box system we are currently using I'm going to build a large brooder that will look like a piece of furniture. I want it to be easier to clean, have more space for more chicks, and most of all I want to incorporate 2 of the 3 boxes we use now, as well as a separation pen in case of sick or hurt birds. Using an old kitchen table, stained glass cabinet doors that were left over from our kitchen remodel, and a couple of plantation style, wide slat, wooden blinds (yes, those thick, sturdy, slick painted (usually white) wood mini-blinds for home windows).
