1. My male oriential frill pigeon has bright green poop, which is slimy and not solid, he also has been vomiting, I feed him cracked corn. He sits with his wings drooping slightly, I have also fed him bird seed at one point but switched back to corn, the other two pigeons have been here for a month and he's been her for 3 months.l 2.My Antwerp make has had crusty mucous outside of his nose and his droppings are solid with the white, but the part that should be brown is greenish, he acts normal but still I fear he is sick. Lastly the female frill has greenish droppings but no mucous. Please help, thank you.
