Hi, we live in Hawaii and 3 hens and 1 rooster have moved in to our yard. 10 eggs hatched about 20 days ago and I just noticed there are 8 new eggs in their nest in the corner of the yard. The eggs are abandoned during the day and at night the hen and her chicks sit on the eggs over night. Could this hen have laid more eggs? Or was it most likely one of the other hens? Will the eggs hatch if left alone during the day for about 9 hours? Thank you for your help.
