Well, here I go again. I just spent 2 weeks medicating my flock of 11 chickens/roosters b/c one of my chickens was coughing terribly. I gave the entire flock an antibiotic which was recommended by my vet. They were on plain water this weekend and I thought I had the problem cured. Now, 3 or 4 more (at least) are coughing...even after being treated for 2 weeks. My question is... do I start the treatment all over again or should a wait another week (or longer)? The ones coughing now were not coughing before I treated them so I don't understand it. The one that was coughing originally isn't coughing anymore. This makes no sense. The product I used was Duramycin-10 and the label says not to administer more than 14 days consecutively. I just wonder when to start back up again or should I try something else altogether?
