I have a young (4 months or so) chicken who I think has sour crop. Her crop is (very) enlarged and feels soft like a balloon. I have separated her from her flockmates and have been putting apple cider vinegar in her water and feeding her live yoghurt and a bit of scrambled egg. I have also tried getting her to vomit up the contents of the crop - while this has had limited success she resists being upside down and I just can't get very much out. Does anyone have any tips on this? The strange thing is that she seems otherwise pretty healthy. She is active and desperate to eat, although her large crop does impede her movement rather. She has been like this for several weeks now (unfortunately I only realised what the problem was a week or so ago) and I feel like I am just starving her slowly to death by restricting her food. She is also pretty miserable on her own. I have been thinking I might just let her out and see what happens. I'd love some advice if anyone can help, most of what I have found relates to chickens who are clearly not happy and need to be taken care of. Also they either get better or die fairly quickly - mine just seems to be carrying on as normal except for a balloon on her front! Thanks.
