Cooler weather is on the way and that means it’s time to prepare the chicken coop for inclement temperatures. Arizona winters are mild, I use an elevated dog house packed with hay for their shelter from wind and rain. As an added measure of protection I hang tarps on three sides of their run. They are free run during the day, but come night they all return to the coop and the gate is closed behind them till morning.
This is coop is considered adequate for mild winters where temperatures rarely drop below freezing.
