Hoping someone might give me some idea of what's going on. About 3 weeks ago during a bad cold snap had a 7 month old ram (american blackbelly) start sneezing blood. Figured it was the cold so we shot him. Looked over his insides, everything was fine except his lungs had clots. Again just figured it was weather. That and the other boys were picking on him. Now today on a warmer day his brother is doing the same out of the blue. He was fine this morning but was doing some fighting as well. Everyone else is completely healthy. Have 3 two week old lambs doing excellent. Just confused as to what's going on. Any ideas? Had my flock for going on 6 years with no issue. Even my mom who raised sheep for years is at a loss. I'm in wisconsin if that makes any difference. Thanks for any advice!!!
