We live in Hawaii and 3 hens and 1 rooster have moved into our backyard. 1 hen hatched 10 baby chicks about 20 days ago. They live in the corner of our yard in a dark nest they built. I noticed yesterday there are 8 eggs in the nest where the hen and baby chicks sleep. The hen and chicks are on the nest at night but the nest is empty during the day when the hen and chicks are exploring the yard. Is it possible the hen has laid more eggs so soon? Or has a different hen laid these eggs? Will these eggs hatch if a hen is not sitting on them constantly? Thank you for your help!!!
