Eggs can look different within the same breed

[jcshirey]

I have 4 hens and all eggs look different! Eggs pictured are, from left to right:
1-Henrietta - Black Orpington
2-Minnie - Barred Rock
3-Violet - Lavender Orpington
4-Henny - Barred Rock

As you can see the Barred Rock eggs are totally different in size and color. They were hatched at the same time.

Eggs size and color are going to be different even within breeds since birds are individuals.
