Oh okay, I’m sorry, I didn’t realize you weren’t sure about the crop. So you know what a full crop feels like, well in the mornings you should not even know it’s there. It will literally be flat. No bump at all. Not even a little bump. Any food left in the crop is a sign things aren’t moving right.I think he's doing a little better but still quite lethargic. What should an empty crop feel like?
I don't see any visual signs that he's having trouble breathing, is there anything I should pay particular attention to in regards to breathing?
Signs of trouble breathing would be shallow breaths or short, quick, breaths. Sometimes gaping can be seen.
Is he hunched up at all?
Has your flock been dewormed or treated for coccidiosis ever?
