She has a history of laying soft shelled eggs. Give her 1 Caltrate with D3 for 5 days, no more and see if that helps with the shell quality.I looked at some picture of salpingitis, does not look like that. Any other idea?
Feed her her normal feed, provide oyster shell free choice, provide fresh clean water. Limit treats.
I agree. Hard to tell if it's a membrane, salpingitis - but not a worm.
