Eggs in Water?

First off I would like to say Hi to all of you and thank you in advance for your input.

WE have 2 Pekings and one Swedish Mallard

our Pekings have just started laying with in the past few weeks and we thought that 1 of them was just a little slow in laying seeing that she has not produced anything yet.

That is until I cleaned out their pond. I raked up 5 eggs that were in the middle of the pond.

this being said I tossed them out because for 1 I have no Idea how long they have been in there and for 2 I dont know if they are safe to eat.

The other Peking lays in the Grass around by the fence.

how do I get her to stop laying in the pond?

Are the eggs safe to eat if I get them out after she lays them?


Thanks again.
