One (or more) of our hens has decided to drop her egg wherever she may be. This started this week. One egg was in the run end of the coop, another under the deck 50 ft away, etc. They've been laying since Dec 2015, now they are all molting, and we live in Arizona. The egg laying has not decreased as I read it would during molt, checked for mites and other parasites and found none. Why are my girls, or one of them, dropping eggs all over the yard when the rest use the nesting boxes? (And there are plenty of empty un-utilized boxes).
