x2, what Azygous said.
It really depends on their personality. When mine were chicks, I've been known to be The Hand of Terror, reaching down into the brooder. I handled them everyday, and they've upgraded me to simply The Hand. Lulu (BO) let me scoop her up, the other two were less enthused, but tolerated. It was best to get my RIR first, since the BA + RIR = Best Friends Forever (to this day). After a few weeks they would come visit and spend time on me (The Perch Man) up until about 12 weeks.
Then a few weeks later after being outside, the hormones kicked in. *RED ALERT* DEFLECTOR SHIELDS AT MAXIMUM! I swear they would move out of the way sensing my hands coming near. It seemed to get worse as the weeks went on, closer to laying. The BO that I used to be able to scoop up with one hand while staying perfectly still was the worst! I would inevitably catch them just to pet them and to do a quick body check and Lulu would raise holy heck. Ruby (BA) always keeps her distance, but once I had her in my lap she just ter ter ter talking quietly, sounding almost like a #itch session about how her BFF (Ruby is ranked 3rd, and BFF RIR Aichan is #1) is always chasing her. The RIR is the most tolerable of the three, but she just would rather be digging in the sand.
I've read on some older posts that some chickens just mellow out after laying and I held on to that possibility as my only hope. Now with all girls laying, it seems to be somewhat the case. Lulu is much much more cuddly, and although it takes two hands, I can similarly pick her up and put her down like the old days. The RIR is a busy girl and has much to do, but won't mind being picked up so much. The BA still has her forward deflectors on at 20%, but if I sneak up I can get her in a squat and she's MINE! ter ter ter
You said treats don't work, but keep trying. Find a killer treat that they just can't get enough of. Raisins, grapes work great for me. The part that's not so great is you should hold on to the treat as they eat from it. Raisins work great for this as you just pinch 1 between your finger, and they tear into it after the soft insides. While doing this, use your other hand to touch their feet/legs, sides, neck... gently, as an exchange for the yummy treat. If you can get them to fly on your lap, even better as it gives you an excuse to be close to them. Other treats work well too, but I must say for the mileage, raisins work the best for this. I can have three working on one raisin pinched in my hand. It's like crack for chickens.
After you get them hooked on crack, pick one up (use a raisin as a lure if you have to) and sit with them. Before they realize that it was a trap, you give them whole raisins to swallow whole. I used to often hold/pet/talk to them while giving them a raisin in plain site and before letting them go, I would give a few extra on the side so that the others wouldn't know. You'll end up getting the others flying up to join you if you don't throw some down to them as well, but for the most part I can keep a one to one session this way.
Just don't go too crazy on the amount of raisins... A small snack box lasts a while. Remember, what goes in, must come out.
