One of my breeding bucks has taken a downhill turn as soon as the hot &humid weather hit. Its his first summer with me. He has gone off feed for 4 days and has stopped drinking. He would "nibble" at fresh greens but not much else. Yesterday I pulled him to force some pedialyte in him and check him over again incase I had missed something. And now hes got himself some discharge from one nostril, sounds wet and looks faintly bloody. . . Do I keep trying? Or do I just put him down and use him for dog food?
