Ms. Bear, note that this is the way I manage my flock. Do I think it's the best way to have a strong, healthy flock? Yes, I do. I didn't say you have to do exactly what I do, but there's no way you can go wrong using this yardstick. Many, like MissPrissy and myself and others I can name on this board, cull for disease. So far, I have not had to do it. Trust me, I raise pets. Anyone who has seen me with my birds knows I love them. They are not just livestock to me. Will it be hard if I have to cull my pets? Yes, yes, yes. I'll cry more than a few tears. Will I do it anyway? Absolutely. If I see snotty noses and matted eyes or hear coughing, the bird willl go. No matter if she's my absolute favorite. Do I cull for one sneeze? No. Too many environmental issues cause that. But I will watch for other symptoms. Observation is critical to head off disease. I never said you have to do what I do or that I know everything. It's not my responsibility to give anyone options...if you read #10, you'll see that I urge everyone to read, study, buy books, consult vets, whatever. I am not personally responsible for anyone else, only my own flock. If I told someone to treat something like ILT or Coryza, it would be against my better judgement. If someone does decide to treat, it's up to them to understand what keeping carrier birds will do to their overall flock health. I'm all about informed decisions here.
