My quietest bird is my lakeside egger Chocolate Mint. However one of my other lakeside eggers, Basil is one of my loudest. All my birds are friendly (with Vanilla being a bit more standoffish but still friendly) but half of them are quite loud
My friendliest bird is one of my easter eggers, Ginkgo, she's usually one of the first to greet me. Lavender another one of my lakeside eggers is basically the flock mom, when my buff orpington Juniper was about to lay her first egg, she and Vanilla were chanting the egg song for her, when Juniper couldn't figure out how to get into the coop (Juniper is very sweet, but she's not the brightest) she came out to guide her in. On more than a few occasion I've gone out to find either one of them with their head tucked under her or she has one or both of her wings covering the birds next to her. She will also hop on my lap to see what I'm doing when I sit with them
As opposed to others, Juniper is one of my best, if not my best layer but everyone in the flock are good layers
