Hi everyone, I have 10 chickens of varying ages between 3 months-2 years. They are all currently sick with a respiratory illness. It started 3 days ago. Some hens are worse off than others. Symptoms are sneezing, coughing, wheezing, gurgling in chest but NO nasal discharge, eye issues or facial swelling. The 2 girls that are have it worse seem a little depressed, wobbly and are not eating or drinking. Everyone else is acting normal except the sneezing, coughing et cetera. I am having a difficult time with diagnosis due to lack of discharge but am thinking it is IB. What do you all think, please help!
