Jenni, those are actually very old pics of him- maybe a year old? Now he's eating 14-17 gram small mice and he weighs 225g I _think_.
My Eastern who is very unhappy now due to having her abcess treated for four months closed-mouth strikes all the time. She won't bite, but she pecks like a chicken! Zee does a lot of probing/burrowing with his pointy nose, which can feel like a bite; however the times he actually bit me (feeding response) he just opened up and started chewing!
