Hatching Muscovy in an incubator is a tricky process. I wish I had the secret sauce to share. Out of the 25 originals in our first batch. We got 1. So, Uno is now 4 weeks old and it's getting close to the time when we need to integrate him with the flock. Our second attempt was not a start - finish deal. We took eggs from ducks who had been sitting for some time. We've gotten 3 ducklings from doing it that way. In the mean time, three different ducks have hatched 9 ducklings. So, Ducks 9 - humans 4 (we'll take the partial credit) There are a few threads here where a few of us have lamented all about the same results. I'm leaning towards long-term storage for the incubator and let momma ducks do their voodoo that they dooooo.... Sorry, terrible schtick humor.
