Ouch...that snake doesn't look like it has ever eaten, and certainly hasn't taken 3 mice in one setting. It also looks like a blood or possibly a blood x Borneo, the pics are a bit ambiguous. Either way, right now the priority is to reduce stress & get that little snake feeling comfortable enough to eat. Lon gave you some great advice above, so please try to keep handling & other interference to a minimum until your python is feeding consistently.

Best of luck!
