I am so sorry. From everything I understand, reproductive issues are not contagious.Thank you. Greta was laying shell-less eggs for a couple of weeks when I also noticed what seemed like a swollen abdomen. Avian vet thought she probably had an infection in her reproductive tract (and thought the extra fullness was fat) so we started antibiotics and anti-inflammatories which seemed to help after a week. But then her eggs went back to no shell and she died a week later. That was bad enough but now I’m finding other shell-less eggs and I’m worried another hen might have what Greta died from.
