It is not a death sentence .. and that is what @Eggcessive suggested.Well, I went to the vet today and she thinks it's MP. She advised that the swab probably wasn't worth it because this is the most common and most likely issue. She wants me to treat with Tylan. So my next question is, have any of you dealt with this in your flocks? My head is spinning over what I was told. On one hand, it sounds really common. On the other the official recommendation is to depopulate my flock. I have so many questions!
