I too have 'trained' the girls to my voice. When they've hidden from the hawk, I can call them. They usually come out. My son and I also use chicken crack(mealworms) to get them. I always feed them a little bit if they do come out. Just shake the chicken crack container and they come running!
Ha Ha...if I ever buy the dried mealworms... They recognize the sound of the lid being screwed open and go nuts even if they haven't seen it
