A couple of weeks ago, I found an egg in the muscovy nest with the shell chipped out of an area about the size of a 50 cent piece. The membrane was not damaged and the chick was still alive. I put a patch of duct tape over it to help keep out dirt and make it a bit stronger and hoped for the best. Well, it hatched last night only a day behind the rest of the hatch. There is a total of 9 of the little cuties in that nest now.
