Getting them started is to get them to eat and make sure they are established feeders before you sell them.
An animal out of the egg can be risky for anyone including someone with experience.
While the majority will eat on their own within 1, 2 or 3 weeks after their first shed some will not it will take longer, some will not start at all and will need a little extra help by being assisted and sometimes worse being force fed than assisted, while in those cases they usually come around within 3 meals it is a stressful procedure.
Than you have the rare case that fail to thrive.
Again ZERO guarantee for something strait out of the egg and not something I would recommend to someone that never hatch snakes and get them started before.
I have a girl I produced years ago that was assisted for 6 months it's extreme but it can happen so it's not to take lightly.
