Well. I put eggs under my Silkie. They were call duck eggs. Day 26 was on Friday. Yesterday, day 28, only one egg pipped. This morning when I got up I checked on the egg, and there was no progress. So I peeled back the shell, and the membrane was all dry. I brough the egg in the house and peeled back the shell, then I took a q-tip and wet it with some warm water and wet the membrane. Then I continued to peel back the shell. All of the veins were sucked up and there was hardly any blood, at the end there was like a pin prick of blood. So then the duckling popped out and is doing great. I moved it into a forced air incubator to dry off. Its yolk is sucked up, I was worried that the yolk wouldnt be sucked up, but it was. The other 3 eggs were already dead, all through the air sac, I wish that I helped sooner. I will post pictures.
