Mike,
When you see mom after she lays her eggs - it's a no brainer (at least for me).
Additionally, I'm not convinced that I could keep temps and humidity bang on during incubation, whereas in an incubator - the temps fluctuate less than a fraction of a degree.
For me personally - I want mom eating right away - she looks so emaciated after laying. I would prefer that she not go another 60 days without eating.
