I think the friendliest chicken breeds are
cochin/pekin frizzle bantams and
barbu d'uccles. I think this because I have raised quite a few breeds, they are all friendly up to laying age, then they pretend they don't know you and run away from you. However, frizzles and d'uccles will still be your lap chicken during laying age! I have a frizzle and a d'uccle who are at laying age, and they love to jump up onto my lap (by choice!!!) and get cuddles. I was just outside enjoying a long cuddle with Thor (frizzle) and Noodles (d'uccle).
D'uccle roosters are also very friendly, I used to have 2 d'uccle cockerels who were also cuddlebugs!
For d'uccles, the peeps on
the d'uccle cult thread can back me up. And for bantam cochins,
@EmmaRainboe,
@Overo Mare or the peeps on
the frizzle thread can back me up.
also, Bantam frizzles and d'uccles tend to make great friends with eachother, and are cute, pocket-sized, and nice to other chicken breeds.
