I am down here in Lavaca County near lavacaw. This past summer was a brutal one and I saw several livestock type animals die from heat. Including a cow just lay over and die. It was an awful summer.
As for my chickens, I have several kinds...BBS Orps, SS, Had Welsummers, EE's, BR and Silkies. I did loose a couple of silkies during some super hot months. I have 3 black Orps that I was concerned about, but ended up loosing one blue during a particularly hot day. I always keep fresh water and had fans running 24/7 in the coops. I think it was just an exceptional year though. Mine didn't slow down laying from the heat, but did with the feed. I ended up switching to Flockraiser from Layenna and they did and do much better.
I do think most breeds do pretty good down here. I think this past summer was just exceptional for more than just poultry.
