Bantam hen with bloody discharge coming from vent?

[Weeg]

This is Lacy. She's a 1 year old bantam Cornish hen.
I noticed some thick blood/blooding fluid dripping from/around her vent before we left for a trip a week ago. This was while I was showing our neighbor what to do with the chickens while I was gone, right before we left, so I was in a hurry. I did check her out and it looked like it was coming from a peck or scab around the vent rather than from the vent, so I didn't worry about it. We got back on Sunday and today was the first day I looked at it again. I did just move this tractor to the far side of our large yard to deep shade before we left, so I have been less attentive to it since it wasn't right outside my door. My bad and now I'm concerned as to what might be going on here.
I noticed it tonight when I checked on them all while roosting. The bloody fluid was very obvious draining from her vent. It is dark so I couldn't get a great look, but it looks to me like it is coming from her vent rather than around it? I've browsed a lot of BYC threads and have never seen anything like this before. Thoughts? Its really thick, so I definitely think its fluid rather than just blood. Could it be a reproductive infection of some sort? Does it look like its coming from in the vent? I do see bloody discharge coming from a spot right above the vent, but I'm hesitant to think that is an injury since there were no obvious injuries before I left. There was only a very small drip when I noticed it a week ago, and I didn't see any obvious trauma outside the vent.
As far as I can tell she is acting normal. Like I previously mentioned, I haven't been very attentive to this pen since moving it, so I'll have to get a better look tomorrow. They have definitely been drinking a lot of water, so I'm hoping that includes her.
They are fed Kalmbach Flock Maker, and before I made the switch a month or so ago, I fed fermented Scratch and Peck. She is definitely overweight being a Cornish. I would separate her and restrict feed, but I don't have a buddy for her to be separated with, and no way to keep her from eating the others feed inside the pen. She isn't horribly overweight, but a bit chunky compared to her bantam flock mates.
Thanks for the help everyone. Really hope this is something I can curb and hasn't been caught to late.

Edit: Our internet is very slow right now for some reason, so I'm going to upload photos in the comments as soon as possible. Maybe try a few more things to get them to load property, but posting this for now.

Well, here we are today. This morning I came to check in her and found a prolapse. Bloody so it was likely pecked by the other chickens. Administered calcium citrate immediately, and separated her. Food and water intake is good and she’s not acting off at all which is good.
I’m so angry at myself for not giving calcium yesterday. Now she’s paying the price.
At this point I’m assuming we’ve got internal laying where egg fragments caused abrasions in the oviduct causing initial bleeding? Now a prolapse from being unable to pass it. If I’m right she’ll likely need antibiotics yes? I have antibiotics for my dog from a couple months ago, can I use that, and if do what dose? I’m send a photo of the bottle in a moment.

It’s difficult to see what going on in this photo. I do believe she can poop.

All the photos look like damage to the vent from picking, but the last one, they really have been at her.

Treat as you would a wound, keeping it cleaned and sprayed.
It would be good to get some photos after it's cleaned up so you can access the damage. She may be able to recover from it and lay eggs and poop normally, hard to know.

Keep her inside and away from flies, they will lay eggs and compound the problem.

Got it. I’m happy to know it’s not a reproductive issue, that was obviously my biggest concern. Wound care sounds less intimidating.
I’ll bring her crate indoors, clean her up and get some better photos.
Thank you!

Well, wound care of a vent is going to be a challenge...poop, possibly trying to lay an egg, etc. You will have to likely clean it many times a day.
A lot depends on how much damage there is whether she'll recover ok or not.

Definitely. None of it is preferred.

I brought her inside our garage and set her up in a mesh pop up pen that is completely protected from flies.
While cleaning the area to the best of my ability, it does look like something is protruding from the vent. The outside of her vent looks intact, I was actually able to lift the upper part up to look at the injury. I have more photos, maybe it’s easier to see with it cleaned a bit.
I have confirmed she is able to poop as well.

Here's how to treat a prolapse. https://www.backyardchickens.com/ar...ng-from-vent-prolapse-oh-my-what-to-do.76124/ If you tell us the antibiotic your dog has, we can tell you the dosage.

Okay, so it is looking like a prolapse at this point. That was my original assumption. I’ll go ahead and treat that.
Here’s a photo of the bottle, looks to be Cefpodoxime 200 mg tablets.

The other thing I’m worried about is stress. When she was in the fog crate near the other chickens, she was completely fine and acting like a chicken. Since I moved her away into the garage, she’s obviously more stressed. I could move the pop up out side next to the run, but it’s not predator proof. And it were not fit well in the mini A-frame tractor she was in. The fog crate might, but it’s not protected from flies. Thoughts?

I followed all the steps in the article minus the hair dry. She was stressed and I wanted to be as quick as possible. I lathered her prolapse with as much hydrocortisone/preparation H and antibacterial ointment as I could, it didn’t want to stick. Put her back in the crate outside in the coop. I’ll either cover the vents with mesh if I can find it, or douse the whole set up in fly spray for horses. Add hdd red is happy to be back near her flock.
I also gave her in pellet of Arnica Montana homeopathic remedy for pain. Dissolved three more in her water.
