Lash egg? Or something else? Is this urgent?

[Martaals]

Just found this in the run, tried googling some and wonder if it might be a lash egg? Or something else? Any ideas?

Not quite sure from which chicken it came, no one is looking ill, but there has been a bit of runny poop lately. I guess my first route of action would be to identify who it came from and get her to a vet, but also wondering about urgency. Is this an a-matter-of-hours emergency? Do I need to make haste? Or is it something which could be a "one off" and I should mostly keep an eye and if it doesn't happen again it was a stress reaction?

There was one hen laying on the nest while I went and refilled the feeder and cleaned up a bit in the run(which is right underneath with a very thin wall). She came out while I was busy, so it might have made a lot of noise and disturbed her from laying. Or someone could be deadly ill, it looks pretty nasty. A bit like an undeveloped egg white with some blood on one side and some white goo on the other side....

It looks like a shell-less egg and it may be defective. What are you feeding, and do you have crushed oyster shell available in a separate container for calcium? How old is she, and is she close to a molt? Do you have some human calcium tablets with vitamin D that you can give the hen when she is identified?

I have had an occasional egg without shell before (at the beginning when they started laying), but this one doesn't have (or perhaps a very thin) membrane. I can not pick it up. And the blood?

I am feeding layer feed, and they have free access to crushed oyster shell separately. They also free range and I see them eating snail shells sometimes. Lately there was a lot of calcium deposits on some eggs so I was even wondering if they are serving themselves to too much calcium, or if the feed has too much calcium in it.

They are 4 hens, half are 1,5 years the other two are 2,5 years. The heb which I'm suspecting to have dropped this is 1,5. She is the only one who didn't stop laying over winter and also didn't molt. Could be she will go into molt now? I don't have a calcium tablet with vitaminD but I could get it. I'm also not a 100% sure it comes from her. I haven't seen it and she isn't behaving particularly different from normal.

Alright, I'll make a detailed photoshoot surgical session after dinner which is just ready

Hens can have various causes for egg shell problems, and shell-less eggs. Since she is eating layer feed, and has access to oyster shell for calcium, I would suspect she is either going into a molt or that she has a problem with her oviduct and sell gland. It can be common. Time will tell if she is getting ready to molt or not, but she is at the right age for her first one. Here is a good article with possible causes of egg shell problems:

Okay, I tried cleaning it a bit but the sand sticks very much. So all the dark stuff is sand. The whole thing is sort of sticky, but it does have a membrane just very thin and sticky, not "dry" like the shell less eggs I have seen before.

The "white part" I cut off and cut in two, and it is the same consistency all over. Sort of soft with a bit of resistance...... Like egg white when it's cooked?

If I open the thing there is clearly egg white inside. For sure it is an egg. But I don't see a yolk. And the white stuff on the outside I am not sure about if it belongs to the egg or if it is attached to it from the outside. I could detach it as you see here. The blood part seems connected to the inside of the "egg".

I tried to cut a bit in the bloody goo, and it seems sort of firm but soft. Darker inside than on the outside.

(before I cut into it)

Anything else I should photograph or look for?

Going into a molt would make sense as she didn't molt yet. But if she has a problem with her oviduct I of course want to help her. I have sent photos to our vet (who isn't specialised on poultry, it's just the one the closest by) and also to a vet further away with knowledge of chickens. I am hoping to talk to them tomorrow when they are open.

From the article you sent it also seems that calcium deposits can be related to defective shell glands. I have seen excessive calcium deposits lately, so I'll make sure to mention that to the vet as well.

But I was wondering if she wasn't planning on molting, the other three did during january/February.

That chunk with the white inside could be lash material.
The 'balloon' contents look very strange, did you(could you) spread it out more?
This also very strange:

Hopefully the avian vet will have some insight.
If none are acting ill, could just be a very big glitch.
