My buff orpington got a badly swollen crop about a month ago. I helped her empty the crop and fed her yogurt for a few days. The crop deflated quite a bit but never really went back to normal. She seemed very unhappy isolated so I returned her to the flock. Now her crop seems like it just keeps swelling and deflating on its own. She seems awkward and walks funny, but eats and poops and lays and gets up on the perch at night OK. But, her crop feels like a beanie baby and she smells bad. What should I do? treat her again? Does this require surgery??
