Hi MerryRobin and welcome!
We're new to chickens too...well I am...DH has had them before

We're in Colorado so we don't get quite the heat you do, but it gets plenty warm. I did quite a bit of research on breeds before we took the plunge and we decided on sexlinks. These are a hybrid, so named because the chicks are differently colored at hatching so you can tell which are hens and which are roos right away. My reason for wanting chickens was to have fresh eggs, DH likes brown ones so I took that into account, I also wanted hardy birds that aren't excessively noisy or flighty, and I wanted a medium to small sized bird that would deal well with cold and heat. Sexlinks are egg laying machines! They're not cuddlers but don't squawk a lot, weigh about 4 to 6 lbs and produce large brown eggs.
I was a bit leery of ordering little chicks and then having to raise them, just because I've never done that. We got really lucky...we're allowed 6 hens where I live, no roosters. I kept an eye on Craig's List and lo and behold...there was a post for 6 red sexlinks that were about 8 months old and had already been laying for 3 months. We didn't have a coop so I asked the lady selling them if she'd keep them for us for a couple weeks while we got one built. She was willing but in the end let us borrow a good sized rabbit cage to use till the coop was ready. It worked out great! Since we got them, we average 4 to 5 eggs a day...today was our first 6 egg day. The eggs are lovely...nice and big and healthy and they taste so good! We've given away over 3 dozen since we got them a month ago and the egg bin in the fridge is full again. We don't breed them, obviously we can't since we can't have a roo, LOL. At some later point, if we were more in the country where we could have more, I might go that route but at present, everything's about perfect as is.
We didn't want to raise the for meat, either. I'm a bit too soft hearted for that

If you only have a few you get to know them too well. As ours get older and stop laying, we'll likely cull them because personally I think it's kinder to end it quickly than to let them just get decrepit and die. At that point, we'll eat them because it would be a waste otherwise, but their purpose is to lay eggs and entertain us!
I'm sure you'll enjoy them; they hilarious to watch and just make you have to smile. I would recommend starting with about 4 or 5...see how it goes and you can add to your flock if you like later on. The heat will be a challenge but there is a ton of info here in the forum and in the heads of the members that can help you out with that. Shade, ventilation, water and good food will go a long way toward keeping them healthy.
