When we got ours, We put them in a closed coop right away with the temperature set up right. I did not pick them up at all, I would just go and sit under the heat lamp and let them come to me. Within a few minutes, there would be the one who got curious and all else would follow. I used to have 20 little chicks crawling all over me and that is when I would pet and hold them. Now when I go into the coop, it is the same. I have full grown hens running and sitting on my feet, while others are trying to jump on my shoulders. All are fine being held including the rooster.
