Let me know how it goes! My hen is eating just fine so I am not too worried. Ok, maybe just a LOT worried.

Send her for a necropsy so you will know what happened and that you will also know if your flock Is at risk. Put her in the fridge, NOT the freezer. You may be able to get it done, depends where you live.Oh and I DID check up her vent.
Did NOT feel an egg or anything else. Did not see any worms.
She did have SUPER foul, smelly, brown liquid come out though.
Anyone know what might cause this? I'm thinking she had some sort
of internal infection that I just did NOT catch in time. Trying not to worry
about my other gals, at this point.
