HELP!!! We have one chicken, Cricket, who's got (almost certain) sour crop. Her crop is squishy, and when you massage it, brown liquid comes up. Or did. Now it's kinda slacking off. She's really, really lethargic: shaking slightly, but not moving. Not sure what to do! She just lies in the grass, face down, her beak opening and shutting slightly. I've read that red wine or apple cider vinegar helps, but how much, and when? We just noticed yesterday that she was not doing well, staying in the coop and standing still. This morning she's been throwing up, and not moving. Please help! We don't want to do drugs, though.
