I think of all the breeds and mutts I've raised thus far, I think the white Leghorns benefitted the most from hand raising.
Mine aren't "cuddly" but then again, none of my hens are I don't raise them to be. My 3 Leghorn ladies get underfoot and used to follow me around the yard hoping I'd turn over a log or something so they could get the bugs underneath (spoiled slightly??? lol). So they can be plenty friendly enough for yard birds.
They do fly well, and can be rather stubborn about roosting on top of the coop or above your head in trees, wing clipping is a must if you don't have them in a run with a top on it.
They are good layers, and so are crosses. I only have 3 of the ladies, but I had a few of their offspring, 6 young RIR x WhiteLeghorn pullets and I was near drowning in eggs there for a while!!! LOL
ETA: this is "Houdini" although in this picture I call her "grandma" just coz she looks it. They are 18ish months old and due to molt soon, and the poor ladies need it!!!
I took the pic with my phone, which doesn't have zoom, so I really was that close to her I just don't touch them a lot. As everyone else says, if you are calm around them they will also be calm.
