We just had our first hatch, and I have a few questions. We have two ducks who are sisters, and they were exposed to our muscovy drake and also a mallard derivative cross (Rouen/Pekin, I think). The first of our hens went broody and sat on the nest for about a week, and then her sister joined her, so the two were squished into the same nestbox, taking turns when they had to break for eating and drinking. About a week before the hatch, the first mom quit. The second duck hatched out two and then left the rest of the eggs. I took them, discarded the half that were rotten/infertile, and now we're incubating the last six, which we guess have maybe two or three days until hatch. I was wondering if anyone else has experiences with ducks sharing nests? I also wanted to know if there is a way to tell if our babies are pure muscovies or hybrids (pictures forthcoming). They're a black/white piebald color like our male (girls are black/white and blue/white), and they've got little clawed toes, but they also have a small patch of color over the eye which seems like a possible mallard-type trait. Also, if the remaining eggs hatch successfully, will we be able to return them to the mom and the older two, or will we need to brood them separately? Thanks for any help.
