2 Eggs, 1 Duck?

[cluckcluckgirl]

I have two female ducks, and one of them is a pekin. The past two mornings, there have been two eggs in a "secret" nest, one exposed and one covered up with straw. The eggs look the same, since the other duck ALWAYS lays filthy eggs right in the middle of the floor. Is it one duck laying two eggs a day? Is this normal or should I be concerned?

If it's happening often then most likely it's the other duck's eggs. It takes quite awhile for eggs to be formed in the body. It would be impossible for one bird to form two each day for very long.
