My chicken has impacted crop that I believe has turned into sour crop (a little smelly) I have massaged and massaged and it doesn't seem to be working. I read that a chicken like this should have no access to food as it can make it worse. So yesterday I took away her food and put her in a cage with just water, with 1 tablespoon of apple cider vinegar in the water. What else would you recommend. This morning nothing had really changed. Should I let her eat later today or what. I don't know how long a chicken can go with no food. She's pretty overweight anyway so i didn't think it would hurt but what would you do? I also bought garlic which I plan on putting in her water later on today that I read online but wasn't told how much to add. I want to avoid the vet if all possible since I just took another there and since I dont have much money.
