Hi! I think it is the heat, too. I have walked all around the pen, but other than an occasional egg on the ground, have not found any hidden nests. I search the yard about every other day. Very frustrating, for sure! Several of these hens are reputed to be 'excellent' egg layers through heat and cold, but sure not seeing the results. This weather has been totally intolerable here this year, but they have shade, mist, a fan in the coop, etc. Maybe it is the heat! It has been a bit cooler the last week or so, but we are heading back for temps over 100 and high humidity the next several days. Sheesh!
