We're building a coop this weekend for our new flock (8). I live in Central Texas. It's already 90 here during the day and there will be several months of upper 90's to low 100's every day (and a minimum of 80's at night). Winter rarely has more than a few nights below 32/freezing. There will be a 6x9 roof above the top of the coop (~3x8), as well as additional shade from the house. I'm afraid it will be too hot even at night to actually close them into a coop (even with good ventilation). I'm trying to build a pretty predator proof run around the coop, out of 1/2 x 1 welded wire (with buried edges or large apron). Question: What is your best hot weather coop advice?
