Hen has a Swollen Vent

[TheChickenLady_2]

Hi, I noticed today that my 9 month old Red Laced Blue Wyandotte Hen (Zinna) has a swollen vent. It has been raining for a week straight in my area, but today we finally had some sunshine, so I went to let my flock out. I noticed Zinna standing in the door way of the coop and not moving. I went over to pick her up and immediately saw that her vent is swollen in a bulb shape and is very heated. The "bulb" is squishy, so I don't think there is an egg stuck in there. I checked my other hens and they all seem fine. I took some pictures of the area and will attach them below. She is also walking funny. It's sort of like a hopping from foot to foot but I think that is because of the way the "bulb" is hanging down underneath her (I checked for bumblefoot and she doesn't have that). I tried to get a good picture of what it looks like underneath her and will also attach that. In addition, she is standing in a weird way which I also took a picture of and will attach below. I haven't seen any of her poop yet, but as soon as she poops I will take a picture and upload it here as well. I have her isolated from the rest of the flock at the moment. Is this contagious? What can I do to treat her?

Edit: Added pictures of her poop

Perhaps it might be mites or lice. Have you checked for that?

I just went out and checked her. She doesn't have any mites or lice.

Has she been laying regularly? If so have eggs been normal? I would check to see if you can feel an egg. Use a gloved finger, lubricate with ky jelly or coconut oil, insert gently 1 - 2 inches, see if you feel an egg. Her stance suggests she's having a reproductive problem, or difficulty laying an egg. If she does poop, get a picture of it.

I'm not sure if she has been laying regularly. I am hoping that since she is now isolated that she will lay an egg and I can see how it looks. I did check like you recommended and did not feel an egg; however, the inside swollen area felt like it was full of poop. As a result of the check, it caused her to poop, so I was able to get a picture of it.
