most mine are super sweet but there are some not so friendly birds in every breed. one is named ms b for a reason but she will still sit with me. the others are super sweet. one demands a "kiss" every night, she rubs her comb against my nose and talks softly to me. my black sex links like to talk with me, love to cuddle and are so funny. i love their color with that green sheen over their black feathers. one even has the feathers on her neck like a spr or a welsummer but they are golden with the black center.
The BSL I got for my mom doesn't exactly like to cuddle, but she's always been polite to us. If I catch her and pick her up, she doesn't fuss much while I pet her or carry her around. Her feathers feel like velvet, too. She's such a sweet girl. And I agree with Birdman - they're great layers! I don't know how much her eggs weigh, but I'm always surprised at how big they are.
I have yet to try a RSL. I've thought about it a few times, but I'm more of a sucker for the breeds with exotic coloring. When I can get some ex-battery hens, I would be very excited if they were RSL's.
