As of 3 days ago, this hen is not thriving: Mostly just stands in one place. 2 days in a row, when picked up and massaged crop area, she threw up. First time food, 2nd time mostly water. It feels like there is a huge fluid build-up in her chest area. Not hard at all. Her neck is held in a more shortened position (if that makes sense). She still hunts and pecks a bit, but seldom and not with her usual vigor. Gave her olive oil with a dropper, which she readily accepted. She will even drink it from a bowl. I don't see her feeding, drinking or dropping much at all, if any. And here's an unusual behaviour -- she keeps kicking her left leg backwards. Not in a usual chicken-stretching-her-leg-behaviour, but a jerky movement backwards. She is not limping at all. When I pick her up and put her on a table to feed, she plops down somewhat off balance. I think she is starving to death. She looks big and feels light when I pick her up. Any suggestions would be greatly appreciated! Thanks!
