Originally I thought it was related to food being a bit finer with the chooks sneezing, that's not the case.. They were sneezing for over a month, not chronic tho, every now and then. Lately it's gotten colder to about 10-15c some times of night which I believed has sparked the sickness Symptoms: 3rd day since the notice of wheezing Wheezing mainly in morning, breathing through mouth more than nose with beak open slightly coughing nasal discharge shaking of head moist eyes less colour in wattles poos mostly normal, maybe a tiny bit runny. Other than that, Almost perfectly normal behaviour. What I've done: The first time I heard the rooster wheezing I immediately ran down to the shops and gave got them OXYMAV B I give them the dosage every day, when they drink it all I give them fresh water with some garlic added as I've read it's good for the immune system and support It seems to be working slightly.. The nasal discharge has stopped almost stopped completely, less sneezing and the beaks are not open. How ever there is still wheezing... I've done as much research as I can, It seems to sound very much like this http://www.shagbarkbantams.com/page22.htm However there is NO swelling in the face, and the eyes are not closing\\glueing together, No obvious loss in egg production, appetite or weight. Should I keep on? with OXYMAV B? I'm on good terms with the local vet so I may be able to get some drugs over the counter (I live in Australia), Can someone diagnose this or suggest some treatment. Thanks! EDIT: I just wanted to add that I just added new saw dust a few days ago.. I've also read that that may cause the wheezing?? so confused, please help!
