What kind of duck egg is this??

[Irishgirl]

I have a duck egg that is a really weird shade of blue, kinda like THIS, and it really has me puzzled. The color is the darkest blue I've ever seen on ANY egg, duck or chicken. It is literally so dark that when I tried to candle it the 1st day in the 'bator, I couldn't even see in side.
If anyone has any ideas, please post them.

Can I get a picture of it? Are you sure it is a duck egg? Just have to be sure

Where did you get this egg? and what breed of ducks did they have?

I candled the eggs last night. the other duck eggs are just spiders, but the blue one is alot more developed. So it looks like somehow a EE egg got in with the mallards.


It looks bigger in the pics, but it's really the size of a standard chicken egg.
