Have you checked them for mites? Or wormed them? I've heard that both of those things can slow down egg laying.Well they started having this issue before the light change i would say in July/August, I thought it was because of molting but it never went away and to be honest has gotten worse. today we got only 8 eggs out of 30 hens? i have lights in there coop and they worked well last year. what kind of lights would you recommend?
any ideas welcome
