Possible egg yolk peritonitis, egg bound, or vent gleet, not sure. Help please

Hi everyone, I have a hen that has been acting lethargic for about 2 days, just standing around and not much interest in food. I didn't think much of it since a coyote had taken her "chicken buddy" a few days earlier, so I though she was just sad. However, today I noticed her poop was yellowish and watery, it kinda looked like egg yolk or something. I also don't know when she laid her last egg. I'm not sure what's wrong with her; egg yolk peritonitis, egg bound, vent gleet, or what. I haven't noticed her "straining" or anything or standing in the egg bound position, however, she stood in a nesting box today for a while, not sure if she just wanted somewhere quiet or what. Her abdomen doesn't seem swollen, but the area around her vent is quite dirty and a little bare, and I may have noticed mites around her vent, which is odd since none of our other chickens seem to have mites. Should I just start her on some antibiotics as a precautionary? It would be great to know what's wrong with her. Thanks in advance!

If you could get some pictures of the chicken in question, the poop you noticed was unusual, and anything else you think is significant, that would help more experienced members figure it out.

Here are pictures of the hen, and the area around her vent

I found this in the coop, it looks like a piece of membrane from an egg, not sure if it's from her though

I forgot to get a picture of her poop before it dried, but here's a picture I found on the internet that looked very similar

TBH, I have no idea how to deal with this. Fingers crossed that someone else will find this and help you out. I would recommend looking up egg yolk peritonitis on BYC and looking for advice that other people shared

Thank you! I'm just not sure how to treat her since I'm not totally sure she has egg yolk peritonitis, but I'll definitely look into other posts about this
