Chucks are best hunted on cloudy overcast days. On hot sunny days the morning and evenings are best. Chucks are curious animals and will pop up
if you wistle. I use an old shell caseing for whisteling. If they are hunted much in your area, they smarten up and head for their hole at the sight of man. Once you are spotted , you need to move to some cover, wait 10 minutes and then whistle.
