Body condition check and feeding question

Hey all! I was wondering if I could get an opinion on my BP's body condition? I know they're supposed to be chunky but I'm worried he's getting too chunky.

He's most likely a Dec 2015 or Jan 2016 baby, male. His empty weight was about 930 grams, as of last night.

Related feeding question: I'm currently feeding him a small rat every 10 days, but since the weather started warming up he acts like he's hungry again two or 3 days after his feeding. Should I move him up to feeding every 7 days or a larger prey size? Or do y'all think it would be better to restrict his food even if he seems hungry?

Thanks for your help!
