Found my hen just sitting lethargic and not moving, eye closed or half closed, picked her up and she just went limp in a way, and puked some stuff up when I tipped her forward. She is now away from the flock and will stand but just closes her eyes, I did dropper feed some water, and felt her crop but wasn't sure exactly what I am feeling for. Notice her comb is flopped over and kind of discolored, I noticed her comb had flopped over a month or so ago and it seemed like she may have gotten picked on a little so I chalked it up to that but it's worse now. She also felt super light and thin to me but her and the others of her breed have always seemed petite to me. I'll attach a pic.
