Taming and Handling Baby Corns
I would suggest starting to handle them when they have had 2 - 3 days to digest their meals and you can't see any bulges at all. If you handle them for about 10 - 30 minutes, more than once on those days just before the next feeding, even better. Usually, they will be pretty wild for the first several minutes while they think you are getting ready to eat them. Hold them over the cage or a garbage can for the first few minutes. Both the exercise and the excitement combine to make them "go" when you first start handling them. When they get older, they will only be eating once per week and won't be so excitable, so you won't get the same reaction. After several minutes, they will probably be emptied out.
If you are worried that the baby might escape when you are unfamiliar with handling it, then just handle it over the top of the cage (or some kind of box that he can't get out of) the first few times. Then if he wriggles away or you accidentally drop him, he will be right in the cage. After the first few times, you will begin to understand how he moves and you won't need to handle him over the safety of the cage any longer.
If you pick babies up at all, it is important to keep holding them long enough for them to stop struggling and to relax. It is important that each session end on a positive note. That is, the snake has relaxed for several minutes and is not struggling or trying to bite. After the snake has emptied itself over the cage or over a garbage can, then sit down for a few minutes with him. Hold fairly tightly when he struggles, but relax your grip when he relaxes, tightening again if he starts to get a little crazy. They are not the smartest animals, but if you are consistent, they will learn:
1. They won't get eaten.
2. They won't get to go back home until they "behave" themselves.
3. The more calm they are, the looser your grip will be.
Don't worry if it strikes or bites the first few weeks. It will likely get used to you soon. But don't put it back in the cage if it "misbehaves" - wait until it is being quiet. No point in teaching it to bite or strike by giving it what it wants (to go in the security of its cage) when it is acting in a way YOU don't want!
If you have ever kept and trained dogs, the principles are the same. Snakes just don't learn quite as quickly as dogs, but they do learn.
