Hello and welcome to the Forum. There are quite a few breeds that do very well here in Arizona. You should pop over to the
Arizona Chickens thread, where we've been discussing the heat and what we do to mitigate losses quite a bit lately. I have three laying hens, three roosters, and eleven pullets at various stages. All of them have been doing extremely well.
I have an adequately ventilated coop tucked against my front fence, side fence and the east side of my house. It gets early morning sun, but gets mostly shade by late morning, so it stays comfortable. Despite that fact, the girls still prefer being in the yard free-ranging. I have oleander trees lining my fence line and usually find a majority of the clan underneath those.
Just for the record, I have: 2 Barred Rocks, 1 Birchen Marans, 3 Black Copper Marans, 3 New Hampshires, 2 Silkies, 4 Ameraucanas, and 2 Speckled Sussex. Oh, and we just added three Broad Breasted Bronze turkeys.
If you are in the Northwest Valley, you're more than welcome to stop by. We're up in in the Arrowhead area.
