Younger is easier for me. I popped my 1900g snake the other day and had a heck of a time!!

You can do it at any age...the question is CAN you do it! Bigger snakes can put up a good fight! I think males can fully avoid being poped if they do not want to be?

Come here little guy. You're awfully cute and fluffy but unfortunately for you, you're made of meat
Right out of the egg is fine. In general, the younger they are the easier it is to pop them. If you haven't done it before you might want to have someone show you/talk you through it in person first.
