My question is this: If you breed a snake now, when will the eggs be laid/hatch?
That cannot be answered, because a female is paired does not mean she will lay egg either , the only timeline is the following.

Ovulation
About 14 days after ovulation: Pre-Lay Shed
About 30 days after pre-lay shed: Egg laying

So on average a female will lay her eggs about 44/45 days after ovulation sometimes a little more.

That's your timeline
