Can ducks and geese crossbreed???

[Ms Clucky]

I was wondering if ducks can crossbreed with geese? I see my male runner duck on my female goose all the time and I cracked her egg open this morning and suprisingly it was fertile. I am confused maybe this can happen? Is there anyway a duck can fertilize geese?

If it hatches, you are going to posts pictures, right? I think you would be the first.

I found this in my Duck/Goose Egg today... She was sitting on it, but the chickens cracked a hole in it.
