I have a 1 1/2 year old longtail rooster who I found huddled in a corner of the coop this morning. I just brought him inside for the night. He has a soft squishy crop, not very full and a bit less full than it was this morning. He won’t eat or drink and passed a small amount of watery green stool. He feels a bit thin with a prominent keel bone. He doesn’t appear to have any respiratory issues and is partly through molting. The back quarter of his comb is blueish. I treated the flock for roundworms with safeguard about 2 months ago. He eats Purina game chow and free ranges during the day. I gave him a dropperful of nutri-drench and scrambled an egg and offered mealworms-not interested. Looking for help for my rooster here.
