Does anyone know (or have opinions) on whether cigarette smoke smell is harmful to new chicks? My neighbor generously gave me a PC fan to circulate air in the incubator I'm working w/ (Hovabator #1582--Estate Sale $3 '.) I have it set up empty to test temps, humidity, etc., & the entire bator now wreaks of cigarette smoke. I cleaned the fan, as best I could, w/ q-tips & alcohol before putting it in. I don't want to be ungrateful, likewise I REALLY don't want to expose chicks to respiratory problems if this might be an issue. Any thoughts or cleaning suggestions? Thanks--this is a wonderful "library" for us newbies! Also, in one of these threads, another BYCer had & used this particular model. (Of course now I can't find the post!) Any specific model suggestions or quirks would be appreciated too!
