Our ladies are free range but this spring we had a lot of hawks flying over our yard and a couple swoop down, so we tried to provide our hens with more shelter around the yard. One of the things we did was remove the lattice work from the deck so they could get under there. Now that it's been in the upper 90s and 100s they have all been spending the majority of the day under there. It's safe and nice and cool for them, but now our egg production has gone way down. We did crawl under the deck to make sure they weren't laying under there. Could it be that they aren't getting enough day light?? They can even get by our crawl space which hardly has any light whatsoever. Or is it the heat (even though they laid really well last summer) or are they not getting enough to eat while they hunker down in there? They have feed in their coop, access to grass and compost, and get fruit and veggie scraps from us daily. We have checked for parasites and looked at their poop...nothing alarming with either. Last summer we got 4 to 5 a day from 5 ladies, now we're only getting 1 to 2!
