Which of these would be the best to help treat my 8 week old chicks with? Tylan, Sulmet, or Gallimycin I suspect that they have Coryza because they have bubbly eyes, runny noses, occasional sneezing, and irritated, sometimes swollen, eyes. Plus they're a little funky. And before anyone says anything: I know, I know. If it IS Coryza they'll be carriers for life. However this is a pet flock of only 5 so I will NEVER cull. I bought Sulmet solution last night and already put it in their water. I WANTED to get gallimycin but my local feedstore only carries Tylan and Sulmet. I just wanted to see what y'all think is better to at least get rid of the symptoms, and get my girls to feel better.
