Hello. I think one of my hens has sour crop. She has most of the symptoms like tossing her head back and forth, large crop, etc. The one that keeps me from saying she has it, is that she doesnt have stinky breath. I used to use hay for the bedding (3 days ago) and I heard this sometimes cloggs them. She eats amazingly well. I gave them yogurt and olive oil (+water today. They loved it. Is there anything else I should give them that will not hurt a bird even if she doesnt have it? Thank you!
