My uncle gave me me two eggs to hatch from his friend's pond (for my niece and nephew). They were set under a broody hen. One duck hatched perfectly fine. The second one not so well. I looked yesterday and it had pipped and today I found it had pushed it's head though and one wing outside the egg. Problem though is that it seems a little premature with blood vessels around the membrane. This doesn't stop there because it is still trying to climb on out of the egg. When it does this though and pushes more of the shell off there is a little blood. I have no idea as I have never hatched ducks. I moved it indoors to the incubator for fear the hen would injure it.
