We found our first ginnea egg in the coop two weeks ago. Two days later we found one on the ground without a shell. This weekend we stumbled upon a nest in the backyard with 20 eggs in it. All the Guinneas free range during the day but roost inside the coop at night. This morning all of the eggs in the nest are covered with snow with isubfreezing temperatures for several nights. Do I assume the eggs are frozen and what should I do with them?
