PICS ADDED Page 2 I'm going to build a brooder/temporary coop, part brooder box, part chicken tractor. I can't take them living til 8 weeks in my living room and I dont' have power all the way out at the chicken coop so I need something to put the kids in at about 6 weeks that will keep them close and warm enough. I'm installing a porchlight on the INSIDE of the enclosed part that I can put a 40w red bulb in to keep the chill off. I'm thinking of a 3 ft by 8ft brooder box, with 4 feet of it enclosed on 3 sides. Lifting lid (4 ft by 3ft) and the other 4 feet enclosed with hardware cloth. Both lids would be plywood so it could lock. I'll add a removable piece of wood or plastic on the inside between the 'run' section and the 'coop' section if I'm having trouble keeping them warm enough, but I figure the chicken bodies and night light will be warm enough in my climate (48 degree low at night right now) Pressure treated wood runners. So right now I have a 3 by 8ft piece of plywood to use as the floor. Still looking for a piece of linoleum to put on it OR do you have suggestions? Should I go back and get some other kind of plywood something cut to the 3ft by 8ft size? I'll use deep litter on top of it. My coop has a concrete floor so I have no clue. thanks for your help!
