You've got some really good advice! All I can add is that once my youngest pullets have gotten used to (and less afraid) of free ranging they want nothing to do with me until they get older again. They'll come up and eat out of my hands occasionally but they won't risk being picked up. When they're at that stage we try to pick them up only when we can do it without stressing them out, and we make sure to reward them a lot for it. And we always make sure they can leave on their own accord. Then they start to learn that coming to us is fun and they won't get punished (like locked up or held against their will for a long time). And the pattern seems to be that once they get older they start to bond with us more again and everything goes back to normal. We always have lap fulls of chickens!
Our go crazy for tomatoes, grapes and watermelon. You can also try plain Greek yogurt, meal worms, sprouted seeds, corn, or cooked oatmeal (awesome in the cold weather).
Only problem with becoming successful at this is you'll have chickens on your lap ALL the time. Good luck ever eating your own food outside again without sharing! Lol
Exhibit A: Sam trying to eat queso in the backyard! Cersei says "Nope, pay your chicken tax!!"
Exhibit B: Sansa helping herself to grapes while I'm distracted feeding the others
Here our some of our newest pullets bonding with me for snacks, they hung out for probably half an hour and jumped off when they were full.
Favorite picture of my man and a bunch of our red sex links swarming him for meal worms!
