I will likely try to pull the one other hen that I think was sneezing this morning and treat her too.
Did you have to cut under the eyes like I read in the link above?

It's not that one is better than the other, they're just different. Tylan (tylosin) will probably work better if it's mycoplasma (CRD), but won't work if it's E.coli or pseudomonas aeruginosa. Oxytetracyline *might* work if it's E.coli, but probably won't work if it's pseudomonas aeruginosa. I guess if I had to choose, I would try giving the Tylan. Here is an antibiotic table that shows the efficacy of various drugs against some bacteria.
Oxytetracyline and tetracycline are pretty much the same. At this point I would try the tylan. If that doesn't work, I would use Baytril (enrofloxacin) instead of oxytetracycline or tetracycline. It's banned for use in poultry, so you have to think about that..
