I call "Llama, llama, llama!! When I go to to see my llamas and sheep, and goat. They hear that and are on the run for treats. I have been using a call to get the chicks use to my voice when food is coming, something they can recognize if the are further off foraging. Higher pitched and quickly, "Come, come, come! Come, come, come!" At times I say "Come, come, come , my horrid little beasties! Come, you 'fowl' creatures!" All with love and light in my voice..Ha! How about you??
