Sagging neck??

Just got a new snake and I noticed its neck seems abnormally saggy... what is this caused from? Is it something to be concerned about?

Thanks

Had he just eaten recently? probably not, I have a girl who appears to be saggy all over, I believe she hadn't eaten in awhile prior to me getting her.

When my red tail eats a large meal her neck will look saggy for about a day. Just think how much there skin stretches during a meal. Sometimes she will be like that before she sheds too.
