Two days later, two wake up with swollen eyes. Like their eyes are swollen shut. I gave them the last of my remaining denagard stash from show season, (only like a teaspoon), and then start oral Tylan 50. I also put Tylan in the water. By day 2, the initial two chicks are now wheezing and gasping, i continue medicating. More chicks develop the exact same symptoms. I buy LA 200, and put that in the water. The month old chick, my favorite, becomes symptomatic, and in desperation, I even start doing IM injected tylan with her. Denagard is of course completely unavailable locally, so from the onset of first birds symptoms tuesday, my denagard arrives thursday night.
