Egg cutting question

[brock lesser]

Do hatchlings immediately begin breathing air when the eggs are full-term and cut? Also, because you'll ask...I incubated at 89° and cut on day 54.

I don't think so,
with all the fluid thats in the egg I think they start breathing when the head pops out of the egg.
Thats my logical conclusion not based on fact though.
