I am a newbie to chicks, get 7 chicks on June 5th. I have built my coop, 8x8 which has upper screened windows on all sides. My plan was to put them in a plywood brooder inside the coop with a screened top. Question is, will my brooder be too hot since all sides are wood? Using a premier heat plate for warmth when needed. Any input would be greatly appreciated.
