I raise Muscovy - but mine are for eating mosquitoes and for meat! They are delicious and not fatty. The males will fight big time - I've had something akin to a murder scene on my deck before as they will pull at each other's heads til they bleed. Once the males reach puberty - I'd suggest culling and smoking - oh on a bed of spring lettuce with goat cheese and pecans - nothing taste finer!
Also - on the ducklings- they take at least 35 - 37 days to hatch and it's difficult to really tell when it begins. So, yours *could* have still been a day or two away from hatching. My gals slowly go broody. By that, I mean that one day, they'll be on the clutch a little while, this will last a few days. It takes almost a week before they are totally dedicating their time to sitting. Also - make sure the momma has some water to splash around in. Most eggs will not hatch in an incubator because people cannot get the humidity right. I have always observed my gals taking more baths right before they hatch out. I've never had any issue with the first clutch from a new mom. Water - a small pool is a must - from my
experience.
Also - it was a double edge sword, but when you wiped those eggs off, you removed the protective layer which keeps bacteria out. It may have been best to leave them alone because removing that clear protective later opens the egg up to everything! Even washing chicken eggs is bad - as it reduces the fridge life of the egg. This is one of the finest articles I've read to date on eggs - I learned a LOT

Right now - I've had issues with the momma's having food and water separate from the rest of the fowl as I free range everyone. Also = I have mine pair up with cochins who successfully hatch out my muscovy and blue swedish meat ducks. I have over 100 fowl running around now so too many lay eggs alongside the ducks and just mess everything up! My gals and their eggs are penned up now but later, I will have them small pools...which will have to be removed after they are hatched. I have ponds too. So - after the ducklings are a bit bigger, I let them all go and have momma take care of them. I do lose a few, but it's the trade off. I want them to forage for food as best they can. I let mine lose too - they always fly back and when they go broody - they stay around the house. Having said that - one of my neighbors has 7 from a hatching that don't want to come back. They have a stocked fish pond with a feeder! but the momma came back and is now on her 3rd clutch in the barn!
I hope this information helps - I do love the Muscovy!
