Hi, There are three different Brinsea minis - the eco, the advanced and the advanced EX. All three of them are listed here: http://www.brinsea.com/products/mini.html Does anyone have the Advanced EX version and if so: - have you hatched Serama out of it? - do 12 Serama eggs fit in the 12-slotted disc that comes with it or are they too large? What are your opinions of this specific bator? Does it hold temperature and humidity well for you? It comes with something called "egg cooling" which kind of confuses me - why would I want them cooled and what is that for? (can't find that info) OR...would it be better to buy an Rcom mini? The only negative side to that bator (and it's a big downside in my opinion) is that it only holds 3 eggs according to what I've seen/read. Thanks in advance.
