Mysterious tiny Silkie eggs!

[Poliwag]

I have discovered 2 small eggs so far and I don't know who layed them.
Here is a picture of the eggs next to one of my Silkie eggs:

The middle one is the first I found which was under the roost and the top one I found today (on the ground as well).

For the past few days I have been getting 3 eggs a day. And here are the ones I know are laying:

Eagle Eyes:

Jess:

Precious (white one at the front):

Princess Puff (only started laying recently):

Here are some pictures of the rest of my chooks:

From left to right, Ducky, Snoopie, Dora, Precious and the last has no name as I think it is going to be a rooster >.<

There is one more Silkie but I don't have a recent enough picture of her yet. She looks almost exactly the same as Princess Puff (almost impossible to tell them apart lol).


Who's the mysterious layer?

If you figure out a way to tell.. Let me know.. Honestly I would go with your newest layers as they typically lay smaller eggs....
