Hello, and welcome! Glad that you joined! I live in the hot desert here in Arizona. Your flock will need to be predator proof but have good ventilation and some shade from the hot sun. Make sure that there is plenty of water out there for them to drink so that they can stay hydrated. It won't hurt to also have a kiddy pool out there with some ice in it when we get the high temps of summer. The ice can melt in it, and they will enjoy standing in the water it makes from the ice.
