The thumb of the other hand is placed on the subcaudal surface (underside) of the tail near the base. The thumb on the underside of the tail squeezes the tail against a finger and, using the thumb in a rocking motion, pushes gentle pressure toward the vent. The increased internal pressure in the base of the tail generated by the pressure of the thumb causes the hemipenes of the males to pop out. BUT I would not do this if you are not used to handling snakes. The best way is to take them to a vet that does herps and asking him to do it! After all that all I have left to say is welcome!
This can be done soon as they hatch out so there would be no need for him to wait 18 months
