How many eggs have you hatched and cut so far?
I cut between day 52 and 55? (that's based on my temps)
Why? Possibility of the hatchling drowning (seen it in person).
Does it happen often? No, however every steps, I take from choosing to incubate the eggs in a incubator instead of letting mom do the job, to cutting eggs are to increase the chances of each and every single hatchling (how selfish right?)
Should anyone just go ahead and decide to cut not knowing what they do? No not recommended like with everything else if not done properly there are risks.
