duck eggs

my muscovey first batch of eggs were no good never hatch see set on them 2 months I found some eggs behind a brush nothing setting on them could it be my male muscovey is not capable of of breeding or could it be my female not capable. I got them when they were 6 months old I think back in january they had there first eggs in june she set on them 2 months the eggs were no good I have found some eggs behind a bush nothings setting on them I do not know if there from my malard or muscovey could my ducks be unable to reproduce I have had my female malard a year my male I got him when he was about 6 months old if I post a photo of the eggs can someone tell them apart and see if there mallard or muscovey.

Bumping up--I sure don't know--but others may.

thankyou

I never had any luck w/ my khaki's hatching out their eggs. They'd sit but nothing. One of my DH's co-workers has muscovey ducks and he has good luck. His set-up is totally different from mine. His nesting coop kinda reminds me of a large size rabbit hutch and run. He has his sitting duck in a coop and 'run' both of which is off the ground. Her nest is inside the coop where she can feel safe and secure. He feeds and waters her in the 'run' so he doesn't disturb her off her nest. After she hatches out everyone, he puts them in another larger area which is on the ground.
Maybe your duck isn't sitting on the eggs for a long enough amount of time? I'm not sure just thought I'd throw this out for ya! I gave up on my khakis ever hatching anything out! I was hoping my silkies would give it a go but alas I ended up w/ all roos!!
Did you break open any eggs early on to see if it was viable? Ours would have the veins but never developed into a duckling.
