What's wrong with my chicken?

[Rostabunny]

I noticed that my black austrolorp hen recently started getting an abscess below her vent. It has been there for about a week.

She also is losing her feathers below her. She is molting quite a bit. Is there something I need to do for her, and what is the issue for both of them?

I attached the images of her below.

It looks like a "breast blister." This is a thread with pictures just like yours, and lots of explanations and links to others so you'll get some ideas for treating it.

Good luck!

Check to see if your roosting bar needs sanding or if you need to pad it. It's not uncommon for hens to rub a place on their keel or breast area and get a blister. It doesn't look too bad, but I'd keep an eye on it.

Below the vent, hard to tell if that bulge is a hernia, fat or ? Is her vent clean with no scabs or wounds?
Again, the bulge, I doubt there's anything you can do but check the tissue now an again to see if there's any scabby wounds that need to be tended to.

Everything seems pretty smooth. This is what I found this morning though:

Looks like someone’s molting, my coop currently has piles of brown and yellow feathers, and 2 of my girls are butt-naked
