I have two drakes and two hens. Ober the last week, one of my girls layed about 12 - 15 eggs in their night house. I just found an egg on the ground right in the middle of their enclosure. Unsure if another hen layed it or if it's from the nest As of yesterday, only one hen has been laying eggs. Is it safe to assume it's a rejected egg regardless of who layed it? Should I just remove it immediately?
