Help, I’ve plateaued with socializing a feral kitten ..any advice?

I’m a pretty experienced foster, and do tnr. I was walking my dog one morning and three kittens ran up to me, they were old enough so I made the decision to hand grab them so I didn’t lose them.

I’ve hand grabbed and fostered over 25 kittens the past 6 months..

I got him, his brother, and his sister in a carrier. The rescue I work with needs weights on them to schedule their in take app.

He let me pick him up but when I tried to burrito him all hell broke loose, I lost the battle and had to go get a tetanus shot. He fucked me up.

The two other kittens were progressing and he was still constantly trying to swat spit, ya know the normal feral stuff. After watching countless. Videos I decided to separate the other two kittens from him and take them to another foster as they were beginning to his and be ass holes like him and he could have 1 on 1 time.

The other two kittens are doing amazing now but this guy still fucking hates me. It’s been a week and half and now he’s starting to attack my hands when I try to open his cage to hand feed.

I am following all recommended socializing steps from countless orgs. I can hand feed him, and pet his head we’ve been at this step for about a Week and he’s still screaming hissing and swatting at me.

When I ask people for advice they send me the the same socializing steps and I’ve watched dozens of videos.

The kitten is now about 9 weeks old.

Is there hope? Is this normal?
