How many days did you give the Duramycin and how long since their last dose?This sounds so much like what my one remaining chick has. Seems healthy other than sneezing/coughing. Duramycin treatment is over and she(I think) still has the same symptoms except the eye is not shut anymore and is clear. Should I go ahead and get the Tylan(?) shot? I am really at a loss any help would be greatly appreciated. Thanks in advance.
