Hello and welcome to BYC!
Glad you joined.
I would focus on Mediterranean breeds and build an open air coop. Chickens are easy to keep but still require a physical effort. If you find that you have difficulty getting up in the morning, I suggest you build a very large run with a roof, 1/2" hardware cloth walls with a predator apron attached to the coop. You would keep food and water in the run and leave the pop door open all the time so the birds can just leave and eat and drink as soon as they are off the roost instead of waiting for you to let them out.
I would focus on keeping them in dense shade or use shade sails, fans, shallow pans of ice to help keep them cool.
