Our 14 wk old black australorp has an enlarged crop that sometimes feels like a bean bag, sometimes like a balloon. We have confined her overnight w/o food & water and it shrinks some, but not completely. It goes from about tennis ball size to about the size of a plum. I am not sure if it is impacted or sour or ?? It never gets rock hard, I don't smell rotten breath. She is eating and pooping. We have tried olive oil and massage a few times (when it felt like a bean bag). Didn't help. We tried baking soda water and tried to "burp" her (when it felt like air). Nothing comes up. We have already spent over $700 at the vet this month for 2 chickens who died anyway. I can't afford another vet bill now. Any suggestions?
