I have a young Muscovy hen (about 8 months) that has been sitting on 14 eggs for 10 days. Last night I saw her going through the yard with an egg in her mouth. She carried the egg all the way to the lake which is over 100 yards and deposited it on the edge of the water. She then broke the egg and ate the contents. She then went back to the eggs and has been sitting fine since then. What the HAY?
