My chickens are still handing the heat well. I've been turning on the misters about noon, and turning them off about 6. The run is getting muddy under the misters, but otherwise its working pretty well. I think that the coop being made of cinder block is helping as well, even in the hottest part of the day its noticeably cooler inside the coop.
I think that Betsey, my Barred Rock is starting to get done with the chicks. She's starting to spend more time away from them, and tonight she was up on the perch with the rest of the flock instead of down on the floor with the chicks.
Egg production is way down again. At most I'm getting 6 eggs a day, and most days its more like 2-4. The only really reliable layers are my Blue Andalusian, Inara and my RIR, Theresa. I'm thinking that next fall, I might start to phase out my other birds and switch my flock over to those two breeds. If Cutie turns out to be a good layer, I'll keep Jayne and see if I can develop a strain of heat-tolerant EE's by crossing him with hens who lay well in the summer.
I re-listed the pullets I still have on craigslist, but so far haven't gotten any nibbles. Which is ok with me, it doesn't cost that much to feed them and the bigger they get the more money I can get for them.
