California Kingsnake not eating?

[FLUGATRON]

Hello!
Sorry to post again but I'm getting little freaked out. I tried to feed my new california kingsnake for the first time in his new home today, but he didn't eat. At first he acted very defensive, but later tried to grab the food offered twice but dropped it immediately. After that, he only acted defensive as if the food was a threat. I tried again later and he just had absolutely no care for the food. I left it sitting in his tank to see if he'd eat it, but he just seems to be ignoring it.

My ideas are that he is either not hungry, or worrying more about me than about eating, he ate the day before I received him (a saturday). Also he could still just be adjusting to his new environment, and I kinda broke the rule to not handle them within their first week, should i just try to leave him as alone as possible for the next week or so for him to get acclimated? It is very possible that I'm overreacting lol, this is my first snake and I just expected him to take it right away being a Kingsnake after all. However, I did remove him from his hide to feed him, so he wasn't to calm and he was moving around a whole bunch so I'll try again tomorrow, any suggestions?

(Btw he has been pooping, but just a few little micro poops. and he is about 16 inches long.)

Thanks,
Caden
