Well, we're still two years or so away from moving to Tucson, but it's always on my mind!
We hope to have a small flock of 6-8 girls for eggs, and wondering what breeds do well in the heat and climate, and are good layers. We really love Ameraucanas. Anyway, when we get there, we hope to purchase some pullets.
Anyway, is there a 'given' as far as breeds for the area?
Thank you!
Two years? That's a long time to wait.

As for the best breeds for out here I will always trumpet the benefits of the Naked Necks. When I started keeping chickens a couple years back I started with Australorps, Barred Rocks and Silkies, all hatchery qualities. All three have done well here, but it wasn't until I switched to Naked Neck Turkens that I knew I'd found my primary focus breed. Not only are they exceptionally hardy and healthy birds, but they're incredibly friendly, feed efficient, and outstanding dual purpose birds who shrug off our excessive heat while other breeds suffer heat stroke and die. Most of my NN hens lay over 200 eggs per year, and they're large to jumbo in size. And don't think you can't get colorful eggs from them. I have NNs that lay blue, green, olive, pink, tinted and brown eggs, and that was BEFORE I started making NN/Easter Egger crosses. I know some people are "turned off" by their appearance, but seriously, once you own them you fall in love and come to see their beauty, and since NNs can be crossed with other breeds you can have a flock of diverse eye candy.
Here's a few of my current favorites from my own flock:
