Yep, they will always lay the same-ish colored egg... Same shape too! I even have one that consistently has speckles...
You can actually use it to your advantage to figure out who lays how many days a week etc.... It can be tricky if you have numerous birds of the same breed, but a close eye can pick up a difference in sheen, shape, and color.
I've got mine down to knowing whose is whose, except the 7 BRs all look very similar.. I've sorted these so we can see how easy it can actually be...
Also helps when I want a specific egg... Lol peaches is my only red star, and she lays the biggest, darkest, prettiest eggs... For some reason, I always grab her eggs, they're big
The white ones are Ancona, the cream ones are Buttercup, there's 2 EES laying right now, one has minty colored and one has olive colored eggs.. I have a silkie that lays an almost purple egg and the other lays cream colored ones.. The Wyandotte's lay a lighter brown but oddly oblong egg, the red star lays the dark brown one, and the BRs are all in the right hand tray, each a different shade or texture..
Don't ask me to tell you WHICH BR laid WHICH brown egg though lol
