Ring around the egg?

[CaptainSamH]

Ok, I'm guessing this will be a quick one, cause folks here are wicked smart....
See the photo;
I've found at least 3 or 4 like this over the past few months, what does it mean? ( or does it mean nothing?)

Moisture changing the color/transparency of the bloom?
If you wet the whole egg does the ring disappear from the shell?

I have one pullet laying eggs just the same. I have no idea what causes that, but sometimes hers are weaker shelled inside the ring. I suspect something to be a tad bit wrong with my pullet because she either lays them in the yard/run (she’s 6 months old) or if she does happen to lay in the nest box the egg gets smushed on one side.

I'd bet the whiter part is excess calcium.
Is the brown part only in that spot...and is shell thinner there when you break it to eat?

Could be she has a 'lazy' shell gland, not turning the egg as it get coated?

Wetting almost always changes the appearance,
'scrubbing' it may give a clue if it looks different after it dries again.

As long as all birds are healthy, eating/drinking/pooping/moving around OK,
I'd not worry about it.

If inside the egg it's all good, I wouldn't worry about it either. I try not to eat any more shell than I absolutely have to!

I have an older girl who often lays eggs very similar to that. They have super thin shells, but they're still fine to eat.

So no change from rinsing and no weak spots.

Might just be the way she rolls.
Any idea which bird is laying them?

This is a “white banded egg”.

this egg stopped in production and tbe next one ran into it. It gets an extra coating of calcium, and the ring forms.

it’s a hiccup in the system, but nothing to be too alarmed at. A lot of times it is caused by stress, like, being kicked out of the box by another chicken, or bullied. Sometimes it’s a constant thing, and sometimes just occasionally.

I have a hen that spent a good 7 months with a white banded egg every two days, immediately followed, sometimes within an hour or two, by a soft shelled egg. Don’t be alarmed if you find soft shelled eggs afterward.

Nah. Is there a way to rig the coop to tell who lays where? (Is that a ridiculous question?)
