When Will Eggs Hatch True From New Mating?

[FoxhallFarm]

Hi all, can anyone out there tell me the answer to this problem.
We recently discovered our Muscovy drake was having an affair with our Cayuga duck.
She is now safely secured in a seperate pen with her own husband.
How long should I wait before using her eggs to produce little Cayugas?

About two weeks--that's how long the female can retain sperm from a previous mating. Good luck, and enjoy the babies!

Mule ducklings are SO cute!

I've owned a couple adults too and they were very pretty & quiet ducks.... Just in case she does hatch some MuscovyX babies

Thanks guys, much appreciated. It looks like I might have some mule babies anyway Bleenie...I had put some eggs in the incubator believing them to be pb cayuga & after candling there are signs of life so whatever they are, they'll be welcome
