Mine are VERY tame, though I didn't raise them from chicks, the youngest I got them was at 4 months. I held them then as often as I could, fed treats by hand, and quickly became the all-powerful food lady earning all chicken respect.
They're not tame for anyone else, Prissy sometimes, if you sit still long enough and talk to her.
When I was at a Flea Market in the booth of a chicken seller, the seller got upset when someone just reached their hand int a cage without talking to the birds first. When he talked to them, they were easy to catch and didn't make a scene. When I bought two hens from him, they were pretty wild, but nice enough when I worked slow transferring from the cages and talked to them. They've since become pretty decent pets for games.
I have 3 out of 6 who jump on me. Prissy demands to be held, and will fly into my lap on command or when she feels like, but she's never ignored me when I asked her. I wiggle my fingers on my lap, and say "Come here pretty girl" and up she comes.
Rooster will ride on my shoulder, sit on the back of my chair, and enjoys having his waddles rubbed (that just sounds wrong...)
Chipmunk is the meanest, it's taken months to where I can grab her, and she still doesn't "like" it. But she's a pig and I use that against her.
Lil'Bit will run towards me in hopes that I have food, and will stand still while I pet her or pick her up... doesn't care at all.
Holding them helps, but it needs to be like twice a day or more. Food works even better when combined with holding. Making them do stuff for the food... like sprinkling it on your lap and they have to jump up for it... that helps.
Chickens rely on sound, so make some noises so they know it's you. Attach a noise to each thing you do... feeding time say something, bedtime... say something else. When you're approaching with food... make a noise. After awhile that noise will bring them running/flying full speed whether you have food or not.
, she loves to cuddle in our arms and sleep on our laps!
