Egg bound, retention, hard boiled egg

[EddieSalita]

I've had one of my older girls, a white leghorn laying hybrid. Appear egg bound. They free range fairly widely. Not sure how long she has been like it. At least a few days, so we did some warm epsom soak, little olive oil on the vent, basic due diligence stuff.
Today she isn't better. But she isn't standing as wide as the last few days. I found this strange egg. Basically a hard boiled egg, or egg within an egg today. Pics below. It had no shell and was very very well cooked. I think that's not the end, as there is a hard egg sized lump still inside her. But the egg isn't peeking out her vent anymore li,e yesterday.

Anyone experienced such an egg deformity before? It seems to go a bit beyond retention. Is this a lash egg?

Are there treatment options?

The hends are fully free range, we have a lot of wild birds and whistling ducks that visit. They are wormed monthly with fenbendazole.

Yeah that looks like what is called a lash egg. It's a sign she has a reproductive infection going on called salpingitis. @Eggcessive can tell you more.

The chicken is not ok. But she is eating and pooping. But mostly lethargic and not herself. Clearly unwell.

Wondering if I should just euthanase her or wait and see.

I live in a rural area. No vet here is interested in treating a chicken.

Please wait till you hear from Eggcessive. She may be able to tell you whether antibiotics can help.
