I have a 3 yo RIR hen and the past month she rarely laid an egg - maybe 2. It's been very hot. But 2 weeks ago I picked her up and noticed her belly - below the vent - was as tight as a drum. Long story short, she had an x-ray and was not eggbound. Fecal test showed no worms. She's barely been eating or drinking unless I handfeed her. Kept her in the house for a week and monitored her intake. She wasn't very active and didn't even try to fly out of the open box when she was inside. Gave her several warm baths with little but yellowy white coming out. Most of her poop is diarrhea. Anyone had anything like this happen? I'm afraid it might be a tumor and not quite sure what to do. Many thanks in advance.
