My white orpington is REALLY talkative and lives for treats, even jumping and snatching them when i try to offer them to the other birds.. My black australorp is a little less talkative, and more docile than the others.. She's less pushy than the white orp but she also likes to come over to me and see if i have treats. She is the most tolerant of being picked up. She tries to shove herself under the other birds at night. The silver laced wyndottes are VERY quiet, almost silent. They'll come over for a treat when they aren't busy doing something else. They dislike being picked up, but one jumped up onto my shoulder once. They seem really intelligent to me. ^Just my experience with my own birds' personalities. Various breeds have different personality types, but individual birds are unique as well. this breed chart lists their different general temperaments and other handy info https://www.backyardchickens.com/breeds/breed-chart
Get an Orpington. I have to many birds to name or im too lazy to name that many birds. Anyways the orpingtons are by far our nicest birds. They love being handled and run straight to me and my wife when we go to the coop. Our Silkies are sweet and calm also but they dont like being handled as much.
I put my hand in the brooder fingers up and my Orpies push and shove to get thier bellies scratched. They will be 2 weeks on sunday. Friendly from day one.
