today i found a nice box to use as my brooder box, its aproxamently 4 foot by 3 foot and around 29" tall. i still have work to do on the coop so i bought 3, i'll use the plywood on the walls of the coop. When i got it home i cut a hole in the top and put 1/2x1/2 wire on the inside of the top to cover the hole. I then drilled a few holes at opossing angles and put small limbs through for roost. I still need to get some pine shavings etc... but i think for 3 dollars it's one heck of a nice box. Did i mention he's got a few more?
