I noticed one of my hens had an extremely large crop. When I picked her up she was skin and bones and the crop was huge. I felt she must have had something stuck in her crop. I wrapped her up and performed crop surgery. The amount of grass and leaves was unbelievable. It was a mass of debris the size of a softball and must have weighed 2 pounds. A lot of pussy fluid came out with it. I removed it flushed the incision site and I closed up the crop and then the skin. She popped right up and is walking around like nothing happened. My question is what is the chance she'll survive and if she makes it what is the odds it will re-occur?
