I thought my chicken had sour crop. Turns out it was secondary to a mass stuck in her gizard. She's been at the vets this week - xrays, medication, mineral oil, etc. Her crop is still rather large but things seem to be moving (she's pooping). Anything I can do to help her crop size go back to normal? Will she always have this extra large crop? Seems problematic. She also seems to want to just gorge herself on food. She's a year old. Thanks for your thoughts.
