Is this LASH EGG?

[Wyorp Rock]

Thankyou for the articles. Im still not sure what I'm going to do with her though. Because she has been on antibiotics already for over a week and then this has happened, I don't know if putting her on them again will treat it or not?
She already hasn't been laying eggs for a long time prior to getting sick so im a bit stumped with what to do with her

Looks like it may be Lash Material.

She just finished a round of antibiotics due to crop surgery. I would not give more antibiotics. You can reconsult your Vet to see what they suggest.
Here's your other thread.

Perhaps the crop problem was a symptom indicator of Salpingitis. Often when a hen is having reproductive issue, there can be other symptoms that might not quite seem so related to some.
