How? Get a gun and a hand call and start calling. Closed reed are probably the easiest starting out.

As for the state law, you'll have to check your states DNR webpage and the rules should be posted. This will also tell you when it is legal to call and what type of gun you are allowed to shoot.

In Texas, other than a license, coyotes are legal using just about anything you want to take them with whenever you want to take them. I forget other states are not so liberal in that respect.

I like early morning/late evening becasue it is light enough outside I can see, but the coyotes are also usually out, either beginning the nights hunt or finishing up.
