My friendliest chickens, as a breed, are my Easter Eggers. I have/had five girls I raised from chicks, and they all were the sweetest girls. Three of them remain, and absolutely love snuggles. I have two EEs that I got as pullets, and they were untouchable at first. Then, after a few weeks, something clicked, and one of them especially is a little love bug. She’ll jump onto my arm if I hold it out, or sit on my lap and be happy. My friendliest chicken overall is a mottled Java, Peeper. If I crouch down anywhere she can see me, she’ll run over, very awkwardly, and demand a hug. Even when they’re free ranging, and there’s yummy grass everywhere, she’d rather have a hug

She goes broody as well, and is the sweetest girl! I hatched some chicks with her a couple years ago, and I could handle them all I wanted, she’d just stand there showing them off like any proud parent. Most of my seventeen girls are friendly, with the Welsummers and SLW being the least nice. I have a little special needs hen that follows me around outside, and we can have a whole conversation

Anyway, just wanted to put my two cents in!
This is Peeper, my Java, sitting on my arm.
And one of my EEs snuggling.
