I have a question on the Brinsea Octagon 20. I am thinking I "need" an incubator and am wondering if this is a good choice? I do not want to spend a whole lot as I will not be hatching often. Is this particular model a good one? Am I understanding correctly that I just have to turn the incubator itself in order to have the eggs turned (instead of handling the eggs directly)? I know you can get an advanced model, but am wondering how the basic one works. I'm considering this one or the mini advance. I see they are both on sale, and both similar in price. Any thoughts or opinions would be GREAT! Thank you in advance!
