The egg changes on the 3rd day

[luckied]

Hello I was hoping I get get some answers regarding egg color. I only have one 5 month old white rock that is laying. She lays an egg 3 days in a row about 26 hours apart then waits for for 36 hours and starts this process again. I found it great that she is very scheduled for being young, but I do understand that egg laying behavior can change over time.

Here is my question - Her 1st 2 eggs are a solid tan color and the 3rd is always a bit smaller than the 1st 2 and it is tan with darker specks on it.
Is this normal? When I say normal I guess I would like to know do others see a consistent pattern in one egg always being different? Maybe it's just because she is still young, but I was curious what others thought.

Sorry if the picture does not show the difference well, but it really is obvious when looking at them.

This is normal.

Slight inconsistencies, especially in the brown coating, are very normal.

Even more than slight is not abnormal...funky looking shell textures, soft or thin shelled, huge double yolked eggs.

Have you seen the weird egg thread yet?
