Back when I used to clicker-train dogs, we'd have "chicken training" seminars. We used a clicker and would give them bread when they did something we wanted them to do (come closer, take the bread from our hands, etc.). The RIRs will go in their nesting box with a hand signal, will follow me back to the barn, go in the enclosed pen with a hand signal, and come when I call them. I've been doing the hand-feeding of bread and clicking with the Plymouth Rocks--the rooster is getting so he'll come running when he sees me. Two of the three hens will now take bread from my hand and one follows the rooster when he comes running. I click when they have approached, and then I slowly move my hand closer to my body so they are closer to me as they take the bread. They take bean seeds, wild grapes, and grape tomatoes out of my hand. I make sure I'm low to the ground, move slowly, and click if they don't "bolt" when I move my hand. Then they get a piece of bread (a cube). They love bread. I also go out when they are roosting and pick them up, stroke them, and talk to them in a soft voice. I've just started "taming" with my two Buffs. They like tomatoes, cottage cheese curds, and bread. I don't have any mealworms, but supposedly chickens love mealworms. I know they love earthworms. All three of the breeds I have are supposed to be friendly, but the PRs were little feral chicks when I got them. I don't know if I'll be successful, but they are getting better. Ironically, the RIRs were the two that had been handled the least and were the oldest of all the birds. And, they are the two that are like little dogs. I could probably put a band on them and a little chain and ride my bike with one on my shoulder (my "adopted" aunt in Germany used to ride with her parrot on her shoulder). I haven't figured out how to house train them...and, I don't think I want them in the house...
