I have two female muscovys setting right now. One has about eight eggs, and one has about 30! They layed their eggs in great places, and it took a few weeks for me to find them. I have two males, a big male muscovy named Big Louie, and a magpie named Lonley Boy who has since gone missing and never returned. If the ducklings happen to be LB's, I need someone to explain the who mule thing to me. They aren't fertile, but do they lay eggs? Need info please! Also, is it apparent from the start if they are mixes?
