Large hard abdomen on laying hen

[Beckaberry]

Hi all, I noticed yesterday that my ISA brown hen of a year and a half old is hanging out on the deck a lot. She has been tail drooped and neck scrunched for yesterday and today. I brought her in today and saw that her abdomen is large and hard. I thought maybe she was egg bound, but it seems that her pathway is clear, at least the two inches I inserted my finger. I feel a large mass under where my finger is, but I don't want to reach in further and do damage. I also don't know if what I'm feeling is fecal impaction or an egg.
I know this breed tend to have egg laying issues since they are bred to lay so many eggs and I'm not sure if this is a manifestation of that or something else. I am looking for help in diagnosing this. I have soaked her in warm water, applied lubrication to her vent and fed her a half tsp of vegetable oil for starters.
Any other advice or help would be appreciated!

Is the enlarged hard area under the vent visible with a picture? Does the whole lower belly feel full like it has fluid, or solid? The drooping tail and being hunched sound like a sick hen. Has she been laying eggs normally? Is she eating and drinking? How does the crop feel—empty, full, hard, doughy, or puffy? Feel it again in the early morning first thing.

Here is her bottom. It looks that way because it's still drying from soaking her. It is hanging low between her legs and is hard! Her crop is empty. Yesterday she ate a noodle and a few minutes after I noticed her lethargy so I haven't fed her anything else, but some electrolytes and yogurt. Honestly, she hasn't laid, but a lot of the girls are stopping right now due to the molt. She's waddling and yes, it is obvious that she is not feeling well. Still talking to me and looking around, but slow and not herself at all.

btw, she is on a heating pad on low so as not to be chilled.

The hard lower belly sounds possibly like she could have a mass inside, such as lash egg material from salpingitis or cancer. Waddling can be a symptom of internal laying or a mass. I would consider seeing a vet. Offer sips of water, and a tonic such as Poultry NutriDrench 2 ml orally once a day would give electrolytes and vitamins. If you should lose her, it might be helpful to get a necropsy to look for what was wrong. Your state vet can do that, and if not possible sometimes a home necropsy may give a clue.
