Thanks for the tag!
As with others on here, I can only speak from my own experience with the breeds I have owned. But I also selected the breeds I have based on the research I have done on breed friendliness!
If you asked me to pick
ONE breed and I had to have all that breed, I would choose Ameraucanas or EEs using Ameraucanas as the blue layer, hands down. I have both large fowl and bantams. 2 LF roosters, 2 LF hens, one LF Americana hen, and 3 bantam mottled Americana chicks and they are ALL just the sweetest and most friendly and personable chickens I have ever owned. All of mine are good with humans, the roosters are good with hens, good with other roosters, and even nice to baby chicks. My Americana hen is so gentle I had to put her with my bantam flock--she runs up to me and wants pets, she likes to sit in my lap and lets me hug her. She is unique though, as she is almost fully blind which I am sure makes her more needy, but she also just has a very mellow way about her.
I would say all of the other breeds I own or have owned are friendly and gentle (Marans, Wellsummer, Orpingtons, Polish, Silkies, banty Cochins, d'Uccles, Wyandottes, bantam light Brahma, Swedish Hedemora, and Olandsk Dwarf chickens). Out of the rest of the breeds the most friendly after the Ameraucanas/Americanas, would be:
Orpingtons - I have or have had Lavender, Mauve, and Silver Laced American and English Orps. My lav Orps were both roosters and while my Lav Orp rooster that I kept was a wonderful boy with me, but he was not very nice to the rest of my family and his brother got rehomed by the people I rehomed him to because he wasn't very nice to them either sadly. My mauve Orp always loves to sit with me and will let me pet her when she's in the mood, she has been a lovely girl since birth. Sweet, docile, mellow, and gets on well with everyone in the flock. My English Orp is also a very sweet, docile and mellow girl but she's a bit more standoffish. She serves as lead hen and I call her "Big Mama". I am trying again with a lavender Orp chick in hopes I get a girl this time, as I do love their sweet and friendly personalities and how well they adapt to a mixed flock.
d'Uccles - I only have one adult mille fleur hen, but also have 2, 5 week old chicks. I have found in general that even super friendly breeds if purchased as pullets or hens tend to be more standoffish with me, and many of my birds are purchased pullets. My MF d'Uccle however, is a very sweet girl that will come and visit me and squats for me and lets me pick her up and pet her. She has never been aggressive to anything or anyone and I just love how gentle she is and that is why I bought hatching eggs to have more. Out of all my bantams I really like their personalities best.
Ranking my other breeds in MY flock from friendliest with humans to least, it would be:
Wellsummer
Wyandotte (always comes to me and sits with me when I visit, but HATES being touched or hugged haha)
Marans (I have a super friendly one that talks to me and follows me, two that are friendly, and 2 that are not and run if you look at them funny)
Polish (still babies, so this is based on 5 weeks of data

)
Swedish Hedemora
Silkies (SUPER duper gentle and docile, but very flighty and uninterested in human interactions)
bantam Light Brahma
bantam Cochins
Olandsk Dwarfs (got them as adults that free ranged, super gentle birds the rooster is even very gentle--just SUPER flighty)
In my limited experience, my bantam cochins have been my second most flighty and least friendly birds in my flock. I raised them from day olds and they were handled a fair amount and just have never come around to human attention. The head cochin hen will visit me and peck at me and has a very sassy personality which I do love, but she will take off the second I attempt to touch her. And the other three (2 hens and a roo) will run from me even if I dare to look at them too long haha. I would like to give them another try, since everyone talks about how friendly and wonderful they are...but I am running out of space!
I have not had a mean bird yet, aside from bratty cockerels that are just doing their jobs. I had for a short time, a bunch of young cockerel Marans that I rehomed as they were all obvious boys at 6 weeks old--they were ALL (6 of them) bratty and would charge at me and peck my hands. They weren't mean, just very easily frightened and reactionary in a more aggressive way. Which of course, counters what many say about Marans roosters...but that was just my experience. They were all from the same set of Marans breeders, so it may have just been that their lineage has a bit of an aggressive rooster streak but I didn't wanna keep them (they were gorgeous though). I just knew if they were pecking me at 6 weeks, they would be even worse by 8 months!
I love ALL my babies, but I would say based on numbers owned, Ameraucanas and Orpingtons are my friendliest favorites!
