Welcome to BYC. Glad you decided join our flock. I would recommend Black Australorps, which are extremely hardy in both heat and cold, calm and gentle (my children and granddaughter made lap pets of them), and the best layers of the standard, brown egg laying breeds. I raised them in the Corning, CA, area where summer temperatures frequently reached 117-118 F (sometimes more), and while my other dual purpose breeds were listless, panting, and holding their wings out, my Black Australorps were going about their usual business like troopers. It's not surprising that they are very heat hardy considering that they are commonly raised in the Australian outback where it gets very hot. Please feel free to ask any questions you may have. We are here to help in any way we can. Whatever breed you decide to get, good luck with your flock.
