Just this fall we have added on to our existing chicken coop and made it into a 16' x 17' Wood's style open air coop and now I'm wondering how I'm going to brood my broilers when I get them in the spring? My brooder used to be about 1/3 of my old coop that was completely closed but now I'm wondering how I'm going to keep the little fatties warm until they go to the outdoor tractor. Does anyone have an in the coop brooder setup or some type of brooder that can be outside in cold weather? Thank you for any advice. I figured it would be a good winter project for the hubby!
