So here it goes posted yesterday got one reply. Just moved to Montana from California 11 hens 2 roosters. Acquired a turkey jake and royal palm hen. Quarantined them properly. I noticed some sneezing in some of my birds even in california...heard was somewhat normal, no big deal then. Last night we got below zero...I have a horse stall converted to a chicken coop, after bouncing between heating and not heating decided to not heat and let them acclimate themselves. Went out just now to offer some oatmeal, notice some of the birds more than before were sneezing. Checked them, no crust or discharge no change in appetite no other signs other than sneezing. Should I treat? If so with what? Or should I let it be. My coop has two doors a big stall door which with the way the draft was blowing towards the roosts, patched that up, there is another one where the boat slip backs to the chicken coop, should I close that one up? The barn has two doors with ventilation windows on either end, should I open any of those slightly, or the coop has two ventilation windows. It doesn't seem to be damp in there, but I just don't want everyone getting really sick.
