Every last one of them stopped 100% for the last two days. They are wondering around like nothing's up, not acting any different. We have had a serious heat streak lately (last week we were at 115 most days) we have "cooled" down to 105. But they layed last week in the crazy heat!! They have access to lots of shade, their coop is under a 50ft ash tree and they like hiding under my kids playground slide and scratched the dirt up there. They have oyster shells, grit, laying feed, scratch, and 1/2 an acre they roam around all day on. They aren't laying anywhere else either. It's like they all lost interest in laying. What on earth is going on and what can I do??
