How do you handle a crocodile?
The thing to do with small crocs to reduce stress is to flip them on their backs. then stroke the underside of the jaw down to the belly. The crocodile will very quickly go into a trance-like state and you can just pick them up and move them about very easily.
When you flip them the right way up and give them a poke they snap out of it.
This may work with big crocs, but getting them to roll over to be tickled may be the hard bit, and I certainly haven’t tried it on anything over five feet.
