I have a hen with a large crop. I thought it may have been impacted and then sour, but I am truly not sure. She has had it for five days now and it has not gotten better. She has been contained the last three days with only a nibble of food today. Poor girl is starving. She is very energetic, wants to eat and be around the others. Crop: NO foul smell Size of large egg Pliable and squishy She burps and gurgles when I rub the crop She also poops (small, little watery, but solid and brown) I have tried ACV in water, olive oil syringe, cinnamon/baking soda/water concoction, no food except today (softened) I am in need of advice since this is my first time with chickens. Any help or suggestions? Thank you!
