When I started out, I called all the time and nothing happened. This was because, I was calling while they were on the limb. From that, I went "shy" and killed a few birds. Now I am less shy and do a lot better. I need to learn to get closer to birds that are on the limb so I can be the first "hen" they want to see. What helped me was hunting with others and letting them hear my calling and saying that it was good enough to kill birds. Up until that, I did not know if I sounded good or not.
