Thank You!
Great advice. Look down the throat to see if there is anything there. It could be coincidence but with two giving wormer and having the same symptoms after treatment the cause is likely to be the worm treatment. Hopefully the coughing will go away soon.
Order the Denegard and treat like chickee said with ACV. The watery eyes and nasal discharge are illness symptoms, either viral or bacterial. The advice with respiratory illness with chickens is to treat it quickly and separate those with symptoms.
I have a good feeling about your chickens recovering quickly!
