Hen has a hole under her vent

[Chickerywitchery]

Found this hen with dirty feathers and since I'm treating another with vent gleet I went ahead and clipped the soiled ones away when I found this dime sized hole. I didn't find any maggots or bugs, no mites either.

The entire area is inflamed, and feels like it's full of fluid. Did an egg rupture?

That looks very weird indeed. Let's check with @azygous @Eggcessive and see if they have any ideas...

It could be that she has ascites/water belly or egg masses inside her belly from salpingitis. It looks like she was pecked, and they have opened the tissue. This is how fly strike or maggots may be introduced by flies. I would separate her, and watch carefully for any maggots that hatch out. I would probably go ahead and soak her bottom in either warm soapy water or Epsom salts water. Then apply some plain antibiotic ointment or vaseline until you get that. Has she been laying eggs recently? What do her poops look like? Are the white urates in the dropping turning yellow? How old is she?

Shes about 2 years old, I went ahead and soaked her after I cut those feathers away and she's eating and drinking. Her poop is watery and a little yellow mucus. I don't know if she's laid eggs recently since I have a large flock but she is standing like she needs to lay one. I've got her in a crate inside with puppy pads and water with a drop of apple cider vinegar in it.
I also sprayed some bird antibiotic spray on the wound after she dried from her soak.

@Eggcessive has taken care of the advice. My advice is to your future photographic efforts. The number one rule is to have your light source shining on the thing you want us to see, not behind the subject which throws what you want us to see in shadow so we can't make out detail.

There isn't detail to be seen, just a small indented hole with a black scab. If you turn the screen brightness up on your device its very clear.

Update on the hen: she passed after 3 days of Epsom salt soaks twice daily, topical wound ointment, and being kept inside on puppy pads. She stopped eating after day 1. Still have no idea what was wrong with her. No maggots ever came from that wound and it never changed.

I’m very sorry that you lost her even with the supportive care. Since hens can suffer from a lot of different issues, including cancer, salpingitis and internal laying, and ascites/water belly which are all eventually fatal. When I lose a hen, I usually do a home necropsy to look at the organs for clues at what caused their death. Most state vets can do a more thorough exam and testing, if you take or send the body in to them.
