I'm re-posting here some info I wrote on an earlier thread:
Chicken idolization is great--There are few things quite as cute as chickens streaking across the yard to meet you when you go outside!
Something I've found to be effective in teaching chickens to not be afraid of people is to linger and pet them right after you fill their food or water (ESPECIALLY THE WATER). They'll "squeal" and jump away at first, but their hunger or thirst will bring them right back. Rub them gently in front of one of their wings or on their breast. It seems they soon associate this stroking with pleasantness also from their little crops getting filled at the same time.
Another extremely effective method for gentling chickens: After catching one, hold and stroke it a while until it calms down. To release the chicken, slowly lower it toward the ground while holding its wings against the sides of its body. If the chicken starts to struggle, immediately lift it away from the ground. Then try moving toward the ground again. As soon as it wriggles again, lift upwards again. Once it stays calm all the way to the ground, hold it there just a couple seconds, maybe give it a stroke, and let it go. Chickens learn that stressing out and trying to wrench away isnt rewarding. Don't ask for perfection at first, but do work for reasonable progress. Most learn very soon (within 4 or so times) to be more calm and relaxed while being handled.
That said, I used to wonder along with others about whether any chickens really liked being held and/or petted. Then I got the tamest batch of chickens I've ever had. They're Large Fowl Ameraucanas I mail ordered from a breeder who told me her chickens are very docile and that her friendliest is one of her roosters. The hen I still have has flown up on my back or arm different times (and does NOT want to get down lau ). She LOVES to be cuddled and nestles her head beneath my chin (see my avatar) and makes happy-hen sounds. She enjoys being held very much. She will often ignore food when I pick her up, evenShe just enjoys me petting her or traipsing around with her.
Sometimes they change a lot as they grow up. This same hen was fairly skittish as a chick. Ive had chicks that were very tame get offish when older.
However, I have found some chickens do not enjoy handling no matter how much you work with them.
