This is first time breeding ducks we got two Muscovy ducks last year and they laid 12 eggs. Four were gotten by puppies before we got the fence fixed but today found one cracked all over and a small tear in the membrane. There is some blood I opened it a little thinking it was dead but it started moving and breathing and peeping. I read to leave them alone if there is blood vessels so I put it on an electric blanket on medium and a damp piece of toilet paper on the top of it. Does it need the crack uncovered for air or not? I'm trying to keep it moist I am in Baja California Sur Mexico and it's about 90 degrees or a little more in the air already and dries the paper towel out fast so I keep wetting it. How often do I turn? Do I need to assist when the blood vessels are absorbed? I don't know what to do this is our first duck eggs I had chickens as a child and they did everything themselves. I kicked out the drake I think he's the one trampling all over the nest trying to breed more.
