Lash egg? Vent gleet?

[Cluck Noris]

Ok so I thought I had a hen with vent gleet. White discharge, poo stuck in matted feathers, redness, and slightly unsocial and inactive. I brought her inside yesterday and started treating with monistat. This morning I thought things were looking better, but this evening I just found what appears to be a lash egg in her pen. Feels rubbery.

She has been eating and drinking, and really doesn't look off. Any ideas? Will lash eggs create a discharge?

Looks much like a lash egg.
Can you get antibiotics?

Cut it open and take more pics please.

I cut it open and it sort of unraveled, and seem like a folded up soft shell. Also haven't noticed any strong odor, and it is about the same color as her normal egg.
