I live in Utah, I am in the process of building a coop at the moment. For those of you who don't know, Utah can get REALLY cold in winter usually getting in the high twenties and 1-3 of snow, SOMETIMES (sometimes) reaching temperatures below zero. Also, it gets REALLY REALLY hot in summer, almost always reaching the high 90s (or higher!) it feels like the sun is going to kill you the whole time. The chickens I am going to get are going to be more heat resilient, because it's more hot then cold. But they are all going to be standard size and they're still gonna have feathers. I have heard that heat is worse for chickens then cold. I know to add ventilation, but are they're any other ways to keep them cool in summer and warm in winter? And will ventilation make it colder in winter. Thank you for taking the time to read this, good day!
