You can use your locator call all day, not just in the morning. Dont get to close on a roost set up, ive gotten within 100 yards without getting busted but that was pushing it. If you get a bird to gobble between 11:30 and 3:00 do whatever you can to get to that bird. They are usually by themselves at that time and looking for love. You wont kill that many birds in camp. I would say none, but once in a while............. Hope these tips help.
