I also love muscovy ducks. (I'm also quite new here!) I've not had great luck keeping my ducks.. they seem to leave, and some have gone to predators. I have only one female and one male that have been great though.She's sitting now, for the third time. Last two times, none of her eggs hatched. None seem viable at all! I'm pretty new to ducks, but none have even been fertile as far as I can tell! Makes me so sad. I'll give her another week or so on this clutch, but then I start taking them away a couple a day til they are gone. I've never found any development. Darn it!!
