What is going wrong with my flock? UPDATE: It's CORYZA !!!!

Julie, I also live in fl and have deal with the sneezing, runny noses, and for a while everyone was on tylan. Then I read a post about how some people don't believe in medicating and those with strong immune systems survive, those who don't, perish. (Natures way?) Unless It is an extremely important one-of-a kind n0-you-can't die on me, I paid ten bucks for this chick, kind of bird, I let nature take it's course. It just became ridiculous how often I was medicating...I now have a stronger flock, and less worry. I do worm them and use sulmet occasionally but tylan is now on the back burner. I personally would not cull unless they were in pain, I have seen miraculous recoveries, and I have seen "totally fine" birds keel over. Good luck, medicate less, enjoy more!!
