Just let our two hens out to free range. One just walked to one spot and just standing still staring. We automatically know something is wrong. They are friendly but would rather not be held. I picked her up and she just stayed calm. When i put her down, i noticed liquid come out of her mouth. Her butt also looks dirty which isn’t normal for them. Did a quick read online about sour crop? An article said to hold them tilted forward and massage the crop for 15-20 seconds so we did and dark colored “spit” and dirt has come out. we have done it 3 times but article said not to do it more than 4 times?? We have her separated with just water. What can we do?! I attached photos. Her crop is definitely enlarged and squishy. The photo in the grass is before we massaged. The photos in the cardboard enclosure are after. She is just staying still and not moving fast.
