Hi my girls stopped laying awhile back. We have dusted them for mites with D,E, maybe twice , dusted the coop cleaned out straw on floor as well as nesting boxes. we did catch a giant opossum in there , but he wont be back. We also have several large garden snakes, but surely they can't be the cause? not for the size of our eggs. Still trying lessons learned before . There was a serious traumatic incident this past winter, but they had almost all started laying again, s idk , either. TY
