White lines on eggs shells

[Iamahz57]

I am getting white lines on my eggs. I have Golden Comet chickens. They do not appear to be calcium. I have attached a picture. I have only had chickens a little over a year. I never had these white lines until I got my newest 7 girls.

Must be a problem in the spray painting booth

Seriously thought it looks beautiful and no egg is perfect , I wouldn’t worry about it , they are not machines .

Enjoy your yummy eggs

nothing to worry about, eggs really are not the same color, exactly the same shape each time either.

Looks like someone scraped their beaks on it while it was super fresh and still wet.

Could be.
Hard to tell on the out of focus pic......could be a poop or excessive bloom smear too.

It looks like you have one of those self-focusing cameras and that time it focused on the pattern on your background. I've run into that problem trying to take close-ups. It is aggravating.

That looks pretty dark for a Comet egg. But since Comets are a marketing name and not a breed name there are no real standards for egg shell color. I'm guessing but that may be one of a pullet's first few eggs. A pullet's first few eggs can be darker than normal. It is not unusual for a pullet just starting to lay to have issues. The internal egg making factory is pretty complicated, sometimes it takes a bit for a pullet to work out the kinks. How many of these eggs have you seen? Are they regular or pretty rare? Do you think it is one chicken doing it or is it regular across the seven new ones?

Have you tried rubbing it off with your thumb? I agree, it does not look like a calcium deposit. If that were chicken poop I would not expect it to be white. The white part of chicken poop is actually the urine, it comes out solid, but I would not expect it to separate on an egg like that. I could understand the splotches being from poop but not the line. I do not think that is the urine part of poop but if it rubs off, maybe but really weird.

That egg shell should be base white with the brown added to the outside during it's last half hour or so in the shell gland. For that to happen in the shell gland something would have be on the egg to prevent it from darkening. That's hard to imagine how that could happen and the shell material being laid down. Are the areas where those marks are very thin?

Did that egg have trash on it so you washed it? I've had dirty eggs with poop on them that the brown came off when I washed them. If somehow a fiber of the bedding got stuck I could see it could take off the brown when you removed it. Maybe she is putting out an excess amount of bloom so the egg stays wet long enough for trash to get attached as it dries? To me trash getting attached would be the most logical explanation but if it is happening regularly it's not very likely. That line is really confusing.

You can get some really weird things with chickens and their eggs, especially pullets just starting to lay. If it is one pullet or hen that is doing it regularly there is probably something wrong with her, maybe in the shell gland. If that is a rare occurrence I put it in the category of "stuff happens". If it is a regular happening it is a pretty good mystery.
