Help with identifying eggs

[BertieBott]

We have a mystery on our hands as to who is laying here! Our girls are just 20 weeks old, but our Speckled Sussex started laying at 18 weeks. Our Sexlink at 19 weeks. We know which are the SS eggs (the small ones in this photo) and the SL (the one at 11 o clock in the photo). However, we don't know about the speckled egg or the dark one at 6 o clock. They look like they are from different chickens, but are they? We have a Buckeye, Salmon Faverolle, Silver Laced Wyandotte, Speckled Sussex, and Red Sexlink.

Thoughts?

Most likely from different birds.

Butt checks might tell the tale.
Vent Appearance:
Dry, tight, and smaller - usually not laying.
Moist, wide, and larger - usually laying.

Pelvic Points, feel for the 2 bony points(pelvic bones) on either side of vent:
Less than 2 fingertip widths apart usually means not laying.
More than 2 fingertip widths apart usually means laying.

Thanks for the reply, aart!

We have actually set up a time lapse camera in the coop today! We know it's not really important who is laying what, but it sure is fun.

Your pointers are very helpful
