What in the world is this

So..this came out of Queenie's butt yesterday. I hope this is not a creature. Is this a lash egg, or an incomplete egg with the chalaza tail?

I should note, Queenie and her mates just finished 5 days of Tylosin water for diarrhea.

Curious. Thank you for placing the Q-tip next to it for scale. Not too many people think to do that.

If you haven't disposed of the "thing", cut into the fat part and see if it has the consistency of a cheese curd. That may indicate lash material if it's a waxy substance. If it's simply flimsy tissue, it could be intestinal lining, although that's usually got a pinkish tinge to it.
