So given that its more feasible with shipping to get larger quantities, i've got multiple incubators. A 3 yr old Brinsea Advance auto min, Brinsea eco mini and Janoel-12 auto. Got the eco urgently when friend donated some eggs. And good thing as the Janoel needs calibration and my temp/hydrometer (10 bucks) not yet arrived. Made discovery **. I think the older model (just prior to the current model) brinsea advance mini or at least mine, is running bit hot. My chicks have been hatching on day 20 and the more trustworthy removable thermometer that came with the Eco read it coming it high. I now have it set to 99.1. The Janoel need -.8- to -.9 calibration so it too runs bit high. Anyone have calibration readings for humidity levels via hydrometer with Janoel-12 water recommendations??
