My year old buff hen started wheezing and sneezing or coughing sounds like a dog bark. She was fine yesterday. What can be done to help her. I removed her from rest of the flock and gave her water with dropper. Also, did the Qtip test for worms nothing seen. Put Vicks under nostrils to try to help with breathing and gave her 1/2 of cc of antibiotic. Breathing was a little better but still wheezing. Is there anything I can get to help with the wheezing. Help needed. Thank you.
