Hen with badly swollen vent area

[Georgia Nana]

I just purchased a heavily feathered Cochin hen that has a badly swollen, red, irritated vent area. There is no foul odor, and from what I have read, if it were vent gleet, there would be an awful smell. I don't know what giving her molasses will do to her system. It is very hot here, and I am afraid to stress her further. Will the molasses purge her system? Is it hard on her system?
I applied myconazole nitrate cream to the area, but am second guessing myself and wondering if I should put antibiotic cream on it.
What should I do?

My hen had something that sounds familiar. In her case the hen's vent was red and distended. She looked like she was trying to lay an egg but couldn't. I thought maybe she had a prolapsed uterus and I tried to push it back in but that didn't work.It felt like a round ball in there, an egg? I picked her up and was washing it in the sink, trying to see if there were any injuries. That's when I noticed that what looked like a ball inside, peeking out the vent hole, was poop colored. It dawned on me as I manipulated it that that was exactly what it was. She was constipated! Looking at it there was only going to be grief for her to try to pass it whole. It was big and I had already observed her trying to unsuccessfully pass it. I could tell it was a mass that was firm but still soft so I was able to pinch it carefully in half inside the extended vent. Then I kind of moshed it down to a skinnier mass and pushed it out and then did the same for the remainder portion. It was definitely poop, there was no blood, or anything sharp. So I just finished washing the area, The vent was still extended though flat and loose and so I pushed it back inside and then set her free. Problem solved.
