Mediterranean breeds are all from hot climates, so they'll be good. Leghorns, Andalusians, Mincoras. Thing is, they're all pretty much white egg layers
. One or two is nice, but most of us backyard folks don't want all white eggs.
Most of your dual purpose birds will do well. It sounds counter-intuitive cause they're black, but Australorps were developed for the Aussie desert and heat, and they do well. Rocks, sex links, Reds, those are all good.
If the naked neck thing doesn't skeeve you out, you might look at Turkens. Not only do they have the naked neck, they're supposed to have less feathers overall, so they'd be cooler.
