I've had many corn snakes, bred Okeetees, & still have 5 (various) corn snakes: your tiny one sounds normal, considering that so many birds would just think "worm!"
& gulp him down. Some hatchling corns are mellow but they'd probably not survive for long in the wild, so just think of yours as a survivor! And just be patient, she'll
more than likely out-grow it just fine, corns are awesome pets, easy to feed & easy to handle. BTW, have you noticed that even if your hatchling corn "bites" you, you
can't even feel their teeth!? they're too small to even break the skin, hahahaha!
Try to imagine being so tiny and confronted with GIANT HUMANS & your instincts say that which picks you up is a PREDATOR-that's where she's coming from, she's
definitely not a "jerk", she just wants to live a while.
