HELP! I don't know what the problem is

One of my 17 hens, all wormed, and overall healthy, has had problems with laying off and one since she first began. She's had them stuck inside, so I bathed massaged to cause it to come out, on more than one occasion.

Lately, she's not been acting too well. Although she eats, she will not "go after it," she's hiding some this evening, but not hunching as though she's egg bound.

I also have noticed that one of my girls, I don't know who, but assume her, has been laying broken eggs every couple of days.

I'm wondering if she's had an egg break inside of her and cause some sort of infection.

Do you have any suggestions?

Her poop is quite runny, she only eats if I put it in front of her and she's slow moving, almost hiding in the way she acts. I have in the house now in a box.

I wormed with Wazine (two rounds) the whole flock late fall of last year. I plan on doing it again this coming spring.

She is now not eating that I can tell. I've seen her take a few bites, but that's it. She seems interested but then turns away from it. She'll be with the flock, but when I set food out, she'll actually leave.

She also continues to have very runny pooh.

I'm not entirely sure how to do a cloacal exam. I have reached inside her and felt nothing out of the ordinary.
As you can see by the pics, her abdomen is somewhat swollen and very red. I feel nothing in it.

I went to TSC last night and purchased Save-A-Chick packets (probiotic) for her. (Here are the three differing things they suggested I choose from.) I opted for the packets and only go for antibiotics later if need be. They also had a liquid antibiotic I could give by syringe. But, as you can imagine, my head is spinning with what to do.




Do you have any suggestions?
