Who laid this egg?

[Cluckatar]

We have five hens that are just reaching egg laying maturity, and today we found a beautiful little egg. There are two barnevelders, a black copper marans, a speckled sussex and a welsummer. Any guesses on who laid this egg? The roosters have been interested in all of them lately. The egg for size and color contrast is from our silver cuckoo marans. I'm certain it's not the sussex but otherwise I'm not really sure. Thanks!

I'm going with the Black Copper Marans.

That looks like a black copper Marrans egg to me! Beautiful!

I was thinking it might be the black copper marans, but at just 21 weeks I was so sure she would be the last of them to start laying.

Gonna be hard to tell with 3 dark layer breeds.
Might have to 'catch them in the act' by nest stalking....
...or this might help too:

The picture is becoming... well less clear. At least three of the young hens are laying this week for the first time. Speckled sussex is for sure that pinky tan egg. Today's egg, however, muddies the water a bit. Our options are welsummer, barnevelder (2 hens) or black copper marans. First picture is yesterday's eggs, including two easter egger adult hens, and one silver cuckoo marans for size and color reference. Second pic is the baby eggs we've gotten in the past three days. Top left corner is new today. It looks like a different hen from the other two brown eggs, no? I suppose it doesn't matter, but I'm having fun figuring it out

My Welsummers didn't start laying until 25-26 weeks, and the breed generally only lays 4 eggs per week. True of my 2. The egg size is still around 50 grams. Slowly getting larger.

There is a post of a gal who paints her eggs by putting paste food coloring in the vent to see who laid what.

I think the dark eggs are being laid by the Black Copper Marans. The lightest are definitely the Speckled Sussex. Now I think the newest eggs (lower right on the left half of pic & upper left on the right side) are probably a Barnevelder? The Welsummer is yet to be heard from. 24 weeks old at this point.

The welsummer just laid her first egg this week at 27 weeks. It's the lower left, light sprinkling of dark spots.
