Soft shelled eggs. Lash material? Reproductive illness? Ascites?

[ChickenMama308]

Aloha everyone!

My sweet 2.5 year old RIR hen, Oia, had a swollen abdomen for at least a couple months that had her having soft poops, eating less, and loss of muscle mass. Her sister died in November from reproductive illness Oia seemed to be getting more unwell as her abdomen enlarged, and the morning I was going to start her on anti-inflammatories, she seemed back to being herself - and when I felt her abdomen it was no longer filled with fluid! It was a wonderful morning Her poops went back to normal and all has seemed great for the past month or so. last week however, she passed what looked like a soft shelled egg /membrane with no yolk... and what is that attached to it? She passed another similar one a few days ago, as seen in final photo. She seems to be acting normal otherwise but curious what this could be / what this could mean. As an FYI - she is 100% free range and I have no idea unfortunately if or how often she is laying eggs, or what they look like. It seemed very lucky that I got to see these, as she passed them near where she roosts.

Thank you for any thoughts / advice

Soft shell, membrane, lash egg material=Possible Reproductive tract infection / disorder.

I understand they are freerange chickens, but you you feed a source of calcium?

Have you tried supplementing your flock with calcium? It’s not likely that they are getting enough to manufacture their egg shell just on a free range diet alone.

Without a source of calcium, chickens pull from their own bones and become calcium deficient.

Where are you located (state/country)?
You free range 100%, so they get no supplementation whatsoever?
I agree with @staceyj provide her with a source of Calcium. It does look like a reproductive problem for which there is no cure, but the calcium may help firm up/harden the shell and help with contractions so she can more easily pass the eggs.
Oyster shell can be found at most feed stores, just put some in a separate container, your girls will take what they need.

What you have in the photo looks like she has Salpingitis. You mentioned she had fluid in the abdomen/large abdomen. It's good that she was able to re-absorb some of the fluid and passed the egg.
If she were mine, I would also treat her with antibiotics. You can use Baytril or Amoxicillin - those may help with infection, but if this is Salpingitis, there is no cure.
