I heard somewhere that over feeding poultry can affect their egg laying ability. I have tried to feed all my birds well, but maybe in doing so I have made them, fat and complacent birds that have no incentive to reproduce. They were laying well in a different climate, so I think that has a lot to do with it. I have provided them with more than enough opportunities to replenish the moisture they may have lost by the low humidity. I gave them a huge wading pool, and large containers of water all over my yard (they free range). but they also eat a lot. Regardless of how much I fed them 30 minutes ago they will always ravenously chow down anything I put out in the feeder, and steal food from the chickens.
