I think you're right with the heat! They finally did lay yesterday (82 degrees) and not today (91!). I did peruse around in the bushes though, too, for good measure. They are penned full time, in a 600 sq ft run![]()
I've had my birds cut way back on laying before and seen a quick turn around after being wormed. If you haven't wormed them in a while it's not a bad idea (especially since they aren't laying well anyway so if you have to discard the eggs depending on what you use for worming at least it won't be many eggs).
