What could be wrong with my chicken?

[BeeJayBird]

I’ve looked through all the posts and I’m at a loss..

This morning I found her all fluffed up, hunched, pink comb, eyes closed standing on a one leg, refused to leave the coop. When I got her out she tried to hide under the coop.

I brought her inside, set up a cage, examined her, gave her scrambled egg, soaked mashed feed and water with electrolytes.

Her crop was empty this morning, vent is clear pulsing as normal, I can’t feel an egg, so I don’t think she’s egg bound, she’s eating and drinking, tail up. No mites, no worms… but she’s still kinda fluffed up, although her comb is returning to normal red.

She’s been broody, I’ve had to break her broodiness once. But this time she was still leaving the coop to eat and drink so I didn’t think anything of it. I did notice she was being bullied by the other hens.

Could she just have needed a break to eat and drink? What could be wrong with her? First two pics of her are from this morning, this last pic is from this evening. Yellow poop is from the morning, 2nd poop pic is from after she ate

Did you ever figure out what was going on?
