...sounds awful but it's not as bad as it sounds. You see my sneezy chickens, I believe, have an infection and I have an ultrasonic humidifier going full blast in my coop with a water-oxine mixture pouring out of it. My coop is small and so I have a small ultrasonic in there doing the job. I closed the run door and the egg and vent doors and the mist suspends really well inside the coop. I hope this works. The birds seem happy and healthy, but it's clear they have something going on in their lungs and nasal passages etc. Who else gasses their birds with oxine? Btw, the humidifier was bought at target and looks like a penguin! Lol my birds find it very interesting, which is good because the mist pretty much blasts them.
