What happens to the eggs that have been sat on that do not hatch Does the hen remove them or eat them to remove them from the nest or predators?

If a hen's eggs do not hatch after the incubation period, she may eventually leave the nest, especially if they are not viable. Typically, hens do not eat the unhatched eggs; instead, they may abandon them or push them out of the nest. In some cases, a hen will continue to care for the eggs until she feels it's time to move on, but she generally avoids consuming them to prevent attracting predators.
