They stopped laying in the middle of summer... Its now fall. I fed them layer pellets. They have ran out of water a few times for less than a day but have since upgraded to an extra water dish. They have been roosting in their nest box.. which leads to lots of chicken poop in the box. I don't see any signs of eggs shells from them eating their eggs. I dont see signs of other critters in the coop. They don't free range much. Any ideas?
