Greetings fellow chick lovers. I just moved my 5 week old - 11 Brahma's outside in their coop that turned out to be more like the taj mahal! I put lino down first liner second, play box sand third and 4" of pine shavings. Yep they are snug and happy. I also placed the heat lamp in the top corner facing to the cneter of the 6X6 coop. I placed their water and food containers that they have used from day one in there where they cannot be tipped over. Here is my question: It has been hotter than, well you get it, 90+ during the days and in the 70's at night in the upper NW corner of GA. Tonight it is to drop to 67 degrees. I do have vent slates at the top of one side at the top of the coop that is 4' high. I was wondering if I should also leave one of the screened windows ( 12"12" ) open so not to over heat, what do you all think? Thanks all.
