I think my hen's vent is infected!!Update, found out what it is!!!!!

I have an 8 month old EE. I noticed when she was preening herself today, that the feathers looked wet. So I checked her out and I think her vent might be infected. She had a horrible smell coming from her, but after washing her rear off, I couldn't find any wounds. All I could find were what looked like greyish,yellowish areas on the edges of her vent. Her vent is extremely warm too, and she is constantly flexing it. I don't believe it is prolapsed, as I have seen this with dogs and cats, at least, and it looks like everything that is supposed to be insided, is. I looked her over thoroughly, and she doesn't have any obvious wounds that I can see. She does stink like infection bad, though. I have read about vent gleet, and wonder if this is it. However, she doesn't seem to have nearly as much yuck as the hens in those pics. She hasn't laid an egg in about a week, but neither have some of my other 8 month olds. Her tummy feels normal, not swollen, and she otherwise acts fine, eating foraging, all that. I wouldn't of even thought anything was wrong, if I hadn't seen her feathers that looked icky and wet. I did see some fresh blood drops on the poop board, when I went to clean it too. Since no one roosts during the day, it had to be from last night. Very good chance it came from her, but not sure. Everyone else seems to be fine. I am so worried about her. Of course, she is my most absolute favorite hen. I would appreciate any help. I will post some pics as soon as I can get some help holding her.
Thanks!

 

I was able to get a picture of her vent. The yellow is actual skin, not caked on poo. The feathers are wet because I had just washed her off. Her poo is normal, she actually pooped when I was washing her butt. It was formed little poos, not diarrhea. She is eating and drinking just fine. Her crop feels good, full and hard. She isn't thin, and her tummy isn't swollen either.
I'd really appreciate any help.

 

No one know what this is?

I called our avian vet, and talked to one of the techs that know ALOT about chickens. She was as helpful as she could be, considering she wasn't looking at my hen. I'm basically doing everything I can at this point. I've cleaned her up, dried the area, feeding her yogurt, I trimmed all the feathers on her tush and have her inside in a large dog crate. The tech told me it was very important to keep the area clean and dry. I will see how it goes, but if it doesn't get better, I should bring her in. It just stinks, because I just don't have the money for that right now. Ugh! I already am dealing with a roo in the house for a mild respitory problem, 4 goats with sinusitis, and medicating them, ( at least one or two of them always get it this time of year) and an old dog with dimensia that really needs a gross mole taken off before it gets infected. Not to mention, after blood work, xrays, and 2 weeks of force feeding and constant care, I just had to have my 12 year kitty euthanized because she had cancer. Boy, when it rains, it pours.

 

Quote:My vet even suggested that it may be parasites. However, about a month ago, I treated my flock with Wazine, than, 10 days later, with ivermectin . So I'm hoping I took care of any intestinal parasites. I do know that I didn't use the eggs for 2 weeks after using the last wormer, the ivermectin. It was very hard throwing eggs away. I had to.......buy eggs at the store!!!!
