I have a hen that is suffering from sour crop. As far as I understand, empying the crop is vital in starting the healing process. However, I don't seem to be able to get the hen to regurtitage the entire crop content and I'm looking for advise on how to savely accomplish that. What I have done so far: with the hen on my lap I held her head down with one hand while massaging her crop. This process caused her to vomint a number of times, but not enough to get everything out. From what I can tell, there are no solids in her crop. Any advise is greatly appreciated. Thanks!
