Since the 3 escaped muscovy hens have settled on my pond and I have 2 in a pen, I have to rotate the drake between the two locations for them all to breed. For how long can a muscovy hen produce fertile eggs from one breeding? Also, my drake seems to be a meat production strain -- solid white and easily twice the size of the hens. Is it likely he'll be able to produce viable offspring without hatching issues? Lastly, what is the most attractive nesting site for a muscovy?
