All 12 of my year-old hens were purchased as day-olds and hand raised with lots of handling - at least, I tried. The five Brown Leghorns absolutely never took to being handled, never accepted treats, ran and hid, and still freak out whenever we get within about 8 feet of them. I mean they scream and fly. The EEs on the other hand, cluster around my feet whether it's treat time or not, and I have to take care not to step on them or trip over them. I don't pick them up or cuddle any of them but one of them looks as if she'd like me to. As for handling, we do that at night, plucking them off the roost. Always have, and they all tolerate it just fine. All five of the BLs survived from day one. I have only 9 remaining of my original 18 EEs. They didn't all go to predators, but some did. Flightiness may not be endearing, but it is a survival skill.
