I have 6 muscovies, pretty sure there are 4 ducks and 2 drakes. We have had fertile eggs, both in the bator and under the ducks. But, after attempting to hatch 3 clutches, all have failed. There are 2 ducks that nest together and fight over eggs, I think they end up getting in and out of the nests several times so I think that explains why they have not hatched any! They steal chicken eggs too as they moved into the coop for the last clutch, flew over the wall and went in where the living was fine! Food and water right there, living large! But, the other 2 ducks have sat diligently and still had rotten eggs! Not sure what the problem is. Planning to sell 2, maybe 3 of the ducks, getting a duck with babies this weekend, she is proven at least and I will most likely keep back a few babies, she has 15 so there should be plenty to choose from! Any ideas about my ducks not hatching babies? Winter care suggestions needed, we are in the process of dedicating a building to the ducks, would have free range days and locked at night. Feeding suggestions? How best to keep water available? How do you know what color they will be when looking at ducklings? And, finally, how do you sex muscovies, or any duck for that matter, before they are old enough to exhibit sexual behaviors/characteristics? Loving my ducks, just trying to get a good working set up for them before the winter hits!
