For me Barred Rocks are by far the friendliest.
Out of seven Barred Rocks in my second Flock, 5 were friendly.
My fourth flock 4 Barred Rocks and 4 Rhode Island Reds.
All 4 Rocks were friendly before 4 weeks old.

My Barred Rocks hop on my knees if I let them.
My first Rhode Island Red hopped on my knee yesterday, no picture yet. 3 haven't at 10 weeks old.
The other chickens in my first and third Flocks were Red sex-links. Golden Comets and ISA Browns.
Most were friendly, but don't like to be picked up and petted like the Barred Rocks.
I've never had Cockerels/Roosters so can't comment on them. GC
