Identify my egg layer!

[Spinksy]

Hello! My Buff Orpington recently started laying, sometimes every other day. The egg on the left was from her yesterday, and I've just picked up the one on the right from the nesting box. A slight difference in size and color (so far her eggs have been on the small size). Could the egg on the right be from another chicken? I have an ameracuana, an australorpe, silver laced Wyandotte, and black star. So far only my buff and leghorn are laying, any input would be appreciated! Thanks

I have a silver laced wyandotte that lays eggs like the one on the right But It could also be Australorp or Blackstar
amerucana Lay blue eggs

You can check there vents a swollen dry vent means they are laying and a pink watery vent means there not.

Likely the Australorp or Wyandotte. You can check by flipping them upside down and measuring between their pelvic bones. One finger width means they are not laying, 2 finger width they are likely laying.

Takes some practice checking and comparing to known layers, and not carved in stone, but a pretty easy way to tell is.....

Vent Appearance:
Dry, tight, and smaller - usually not laying.
Moist, wide, and larger - usually laying.

Pelvic Points 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.
