I hear that used incubators collect a lot of bacteria. A lady i work for gave me her old incubator and turner (Little giant series) The turner looks like she never took it out for hatch time an like she never cleaned the incubator. I cleaned everything up, but the styrofoam i hear just holds the bacteria. Also one of the corners of the bottom peice of the incubator is broken. Should i keep the turner and just get a new bator, use it all, or start all new.
