My chickens have access to pretty much anything in the yard. One has come down with a inflated/impacted/sour crop. I held the chicken upside down to drain it. The funk that came out was absolutely disgusting, mostly liquid bt the smell was like something died. Alot came out. At first the crop felt lie a big waterballoon, but after I drained it, I can feel the septic stuff swishin around. I was hoping it would all fall out as I held the chicken upside down and squeezed the crop. I did get alot of fluid out tho. What else can I do? Its a cuckoo maran and one of only 2 that I have.
