Today I am going to put up a tarp and help them out.Hey Jess
One thing you should consider is adding some type of shade to the run. Maybe hang a tarp or something on the sunny side of the run (west?). I do remember how warm it was in the afternoon, but it was really the sun beating down on me and not really the 'heat'. If there was shade on that side it would have made a big difference.
My birds don't have any tree anywhere close enough to provide shade. They spend almost all their time in the shadows cast by the coops themselves. We've had nearly three weeks in a row of 95+ degrees - with another week of the same on the way.
Most of our customers are friends or cow-orkers ..erm... co-workers. If we're currently out of inventory, we simply tell them, "I'll get you your two dozen on Monday" or whenever. They are just about all fine with that. They understand that the heat reduces the production.
Three days in a row now I've gotten a really small egg. Something I"d expect from a pullet just starting to lay, only I don't have any pullets who are at POL. I don't know if the heat is the cause, or if this is a broody hen who's starting to lay again.
