Egg Chart for Ducks?

[Wifezilla]

Anyone have a link to an egg chart that shows a photo of different eggs laid by different breeds?

I have a buff, a runner and a khaki, and as of this morning, all are laying. The eggs look about the same color, size size and same shape, so I have NO IDEA who laid what

First egg is from my Runner, second from my Campbell, third from Welsh Harlequin
