If your hens are eating eggs, the hen will usually have dried yolk on their beaks and sides of their heads. Egg eating hens also can be seen scouting the nests for freshly laid eggs to consume. If you do catch an egg eater, cull her from the flock at once. Egg eating is a bad habit that will multiply the longer you let it continue. If one hen starts eating eggs, other hens will soon follow.
Prevention is the only proven treatment.
Collect eggs often and collect eggs early in the day. The longer the eggs are in the barn, the better the chance it will be broken or eaten. Visit Virginia Cooperative Extension .
