Sour crop help! One of my hens has sour crop. I have been trying to empty by massaging it and etc. But she has been vomiting very little portions. How long do I continue the process? I don't want to stress her too much so I have been taking 7 minute breaks after each time she vomits. This is my first time with this issue and I am unfamiliar with how quickly her crop should be emptied. Any advice is welcome. Thank you in advice!
