It just depends on the chicken. I have 4 Easter Eggers, 2 that I hand raised from 1 day old and 2 that came from an Amish farm when about 5 months old. None of them particularly like being picked up, but the two that I had from a younger age will run up to me for treats while the other two hang back and wait. It is much easier to pick up/handle them once they are older/mature and do the squat. And I found once they got closer to egg-laying age they got more interested in me and more friendly, to the point of jumping up in my lap and sitting beside me. But even my brat chicken that yells for me constantly and wants me around (mostly to feed her treats) doesn't really appreciate being picked up and will fight it.
About 3 weeks ago I brought home 2 Dutch bantam pullets that were right at one month old. They were raised by an Amish boy, and I can tell that he worked with them quite a bit. They are super friendly, will run up to me, jump on my lap, bounce up and down peeping at me, and look for my hands. If I pick them up, they melt into my hands and fall asleep. Never did my bigger chickens do this, even though I worked with them when they were little. Now if anyone comes over to see the birds, I hand them a melting mini chicken to pet and leave the bigger ones (who are usually hiding and chattering about someone new being around) alone.
Just keep doing what you are doing. Patience goes a long way, because birds don't do anything or learn anything by force. Just sit and hang out with them, give them treats, and see how things go when they're a bit bigger.
