Hello All! I have a five year old Old English Bantam named Squirt who has sour crop. Here is what happened. Last night she was just fine and chirping with energy. This morning however she had these symptoms: Droopy wings, lethargic, head down, “poofy”, diarrhea, and a squishy crop with liquid. Her crop was like a small balloon with no hard bulges in it. I separated her from her flock mates in a cage indoors with only water. I tried to get her to vomit. I was very careful during the process. No matter how hard I tried massaging the crop she would not or could not vomit. When her beak opened, I could smell one foot away a horrible sour stench. Here are some questions. I researched that a change in feed can affect the crop. I fed my chickens some unflavored oatmeal last night. Would that throw off the balance of the crop? I have not dewormed my chickens recently so I researched that not deworming for a while could be the source of the crop problem. Should I deworm her now? If so, would the dewormer get digested with the full crop? What dewormer do you suggest? If the sour crop has set in already, what medicine should I use? When should I start it? What has worked for you? Does she need a crop sling because of her old age? Possibly slow crop? What should I do first? Squirt is a very friendly hen. I love her and it would be devastating if she passed away. If you have any advice please respond. I would greatly appreciate it! Blessings Thank you to all in advance!
