Hi! I have a young and super friendly hen who might have an impacted crop. The mass in her crop is almost the size of a baseball and very hard, I tried massaging it and it barely morphed the shape. I've had her off of food and drinking water with Apple cider and Apple cider vinegar in it for 24 hours. She is still energetic and very hungry, wanting to eat pellet feed at any opportunity. She is pooping but the mass is not getting any smaller, and she has trouble swallowing. Will a laxative help break down the huge, dense mass?
