Losing birds!

[Eggcessive]

Di-Methox or Albon which are brands of sulfadimethoxine, is supposed to be good for symptoms of coryza. Sulmet can also be used. But I would cull for coryza. You would be treating birds forever with that. This comes in liquid and powder: http://www.jefferspet.com/di-methox-drinking-water-solution/camid/liv/cp/A2-DB/

You're right, I did forget about Sulmet for treating Coryza, but of course, as you said, I would also cull for Coryza. I just would cull for any carrier disease. The problem is that most of them are.
