I am considering buying the brinsea cabinet incubator that holds 190 hen eggs. I am wondering how people have a hatch going on inside the same incubator as incubating eggs? How do you have the humidity high enough in the bottom of the incubator to hatch the eggs while keeping the humidity down for the incubating eggs? Also, does anyone know of any kind of coupon codes for this incubator? saw a code on here before that was MOAC2010 but the site won't let you use that now. Thanks in advance!
