INFECTIOUS CORYZA... AKA Acute Respiratory Disease (common cold for humans) No, humans can't catch it from their chickens. Symptoms: bubbles seen in the eyes, gurgly sound with breathing, swelling around the face and eyes. There may be hard yellow 'gunk' underlying here. It gets tricky knowing weather this is a routine Coryza outbreak or something like MG/MS. The only way to actually get a true diagnosis is having a bacterial culture performed by a vet. Chickens acquire this disease by direct transmission from an infected bird. This is why biosecurity is so important. Treatment includes Erythromycin and oxytetracycline in drinking water.
