I have read all the posts I can but have not found an answer. I have a flock of 20. Mixed; olive egger, rainbow Dixie? Salmons silkies. About August some started to molt. They all quit laying. Every one of them! Two of my silkies are in another coop so it’s not the coop. Their food wasn’t changed, nothing was changed. Now it’s almost November and I’m getting maybe 1 or two eggs a day if I’m lucky. I have added cracked corn to their morning sunflowers and to their feed. I’ve started layer booster vitamins in their water. I took their nesting boxes out cleaned everything throughly and treated them them for parasites and worms. I don’t know what else I can do. Also they have all the calcium they want. I know they don’t have a hidden nest, they’re in a run. Anything I’m missing?
