I am in MO and it got to 106 degrees last week. I am just building my coop and pen so i cannot say so for sure but i plan on my being in a shaded area without explaining to much until later. Depending on the coop and nest location; even a covering of anything(plywood, foam sheeting) will dissapate the heat.i let you know more after i get mine going.Good morning! I have a question for those who have the metal file cabinets and are making nests out of them. Wouldn't the metal get hot during the summer months? I live in S. Texas and we are in the 100+ temps. Just curious.
