One of my hens has been sitting on a clutch of eggs in a big patch of poison ivy for about 3 weeks now. When I first discovered her clutch there were about 18 eggs. We have a rooster, so I assume the eggs are fertilized. Does this mean all the eggs are going to hatch with a clutch that large? Also, I never see her leave the eggs for food or water. Is there a chance she will starve to death or die from lack of water? We usually gather any eggs we find that the hens lay in the woods, but we decided to leave this hen alone. Should we try and move the hen and her eggs to our nesting boxes inside the coop, or just leave her alone?
