i have 3 around 7 or 8 week old chicks and they really want to sleep on top of the chicken house. is this ok for them? the top of it is tin we live in alabama and its not that cool at night now. i didnt know about the dew falling and them just being out in the night air CRAZY HUH?? any suggestions? i had been taking them down and putting them in their little place to sleep. i have 3 biggger ones in the chicken house but they are mean to them so i dont know if they can sleep together or not. so the 3 little ones are on top and the 3 big ones get the inside. help!!!
