I put a sprinkler in the run and my chickens love it, in particular the Cochins. They like to make little hollows in the damp ground to lay in after it is turned off, and all the chickens like to wade in the run off. Obviously it wouldn't be a good idea in damp areas where the feather foots would stay wet, but here in NM they dry off quickly, and all seem to lay much better. I don't see them panting anymore.
Luckily I inherited a great chicken house when we moved here, and that also keeps them very cool. It's an old wood cow shed that has been insulated with sheets of lead and old feed bags, and has a cedar chip floor that stays cool. It also has a large box fan above one of the doors. I'm hoping they will stay warm enough in the winter. It has its own power supply, so I plan on putting a few brooder lamps in there.
