This is my Drake Hank. What I know for certain about him is that his dad was a black Swedish. Mom could have been khaki Campbell, Blue Swedish, or one of four Muscovy. I realize the odds are pretty good that he is a Muscovy cross and would therefore be sterile. But right now I have three girls sitting on nests with dozens of eggs. What am I looking for when I candle to see if any of them are good? My ducks live on a lake where they are visited by wild ducks, and I know it's uncommon, but I do have one hen that is a cross from one of these wild ducks. I don't want to get rid of viable eggs, but I also don't want to deal with infertile eggs that have been sitting under a hen for 35 days.
