When to Cut - Low Incubation Temps

[BHReptiles]

I would just ask them what day they want you to cut their eggs.

I have. I'm just waiting on them to let me know their rough incubation time for their other clutches. The eggs looks plump, so I'm leaning towards waiting until day 70 or so. Just trying to get a feel for their average incubation time.

For what it is worth, I would Just wait till that first snake penetrates the shell then cut open the rest. I usually determine when to cut mine by observing the pip time of other clutches incubated in the same incubator.

The problem is that they've lost a clutch from this same pairing due to being unable to get through the egg. They are trying to prevent that this year. Because of losing the whole clutch, I don't want to wait and hope that one can pip.
