Probing doesnt hurt the snake if done right.
Popping can be dones straight after hatching but can be very hard to do and unreliable once the snake has enough muscle control to prevent it from happening. After a wekk old I would recommend probing it.
There are people you say they that they can sex by looking at hemipenal buldge but i havent the experience to say whether this is reliable or not as i havent taken the time to see for myself, but the guys who say they can are some very experienced individuals.
Or... wait another year and put it with a male or female.
Jungles like a fight, if you put a male in with your
jungle and they fight, its a male, if it is put with a female and mates its a female.
Personally find an experienced person to sex it, doesnt hurt the snake in the slightest.
Best regards
