doing some feeding at the moment..

I tried charging my camera batteries but unfortunately they didn't charge for some reason I don't know why

Right now I'm feeding some worms to my 2 northern redbellies Tic & Tac, and my 2 checkereds Ping & Pong. One of the checkereds just shed and showing off by being out in the open which is awesome because that one is the hider.

I noticed in pictures that some people chop up worms into little bits and put them on a plate for the snakes to scramble over. but I cut them and tong feed it. What are the pros and cons? Maybe plate feeding would be easier with the adults?
