What to do with very aggressive garter

[EKS56]

My Blackneck female has taken a notion to bite. I have been feeding her in her cage but have started changing containers to feed her in the hopes it gets better.

I can't get the cow into a container without her drawing blood. All my others are fed in separate containers for practical reasons. I just don't know what her issue is she's totally crazy. I think she just likes keeping me on my toes.

Honestly, I think that some snakes really do take care when they're eating. My blind guy has accidentally bitten me before. He's big enough to do a good bit of damage, but never has even left a mark when he bites.
I have others that go absolutely insane when it's feeding time. They're fine 99% of the time, but when food comes into the room they go nuts. They'll attack things that they normally identify as NOT food. Like decor. Or the tank wall.

Could be she realizes you're there and you're not going to try to kill her, but now she's getting defensive over food? Like wanting you to get away from her food or something? Could be it's a positive step that now she realizes you're not going to eat her, she feels like she needs to compete with you...
