You can only do it with brooder chicks. They are in my laundry for the first 5 weeks , once I introduce treats they are all over me. I put my hand in , palm up wiggle my fingers and say " here chicky chicky " before long they are happy to stand with your hand under their belly, giving them a scratch. Now that they are out in the big pen, as soon as they here me calling " here chicky chicky " they run to me. Walk all over my feet and give my visitors a thrill.
