OK guys, here we go----
A two foot square by four foot long live trap with live rooster in the back is deadly on bobcat, but not too sucessful on coyotes. You don't want to live trap coyotes in summer with method I am going to reveal, because they are non-stop fighters and many will be dead when you check your traps because they get over heated and have heart attack or something. You also want to check the laws in your state concerning the sale of live coyotes. I could not find any legal way to do it in Iowa. Snares are best live catch method. You have to place a deer stop on your snare so that loop will not close any smaller than three inches. This will prevent most choke downs if you set your snares in area's free of brush or trees where they can entangle. Use five foot snares. You can set up the snares just like I described in earlier thread on snaring coyotes in CRP fields. Remember the pickup tracks and the large draw station? You can also set snares in their trails where they go under or through fences, but set back far enough from fence so that coyote does not get entangled in fence. You can also use padded jaw steel traps, but you will still get a few broken legs that way. People who buy live coyotes, demand coyotes that are free of foot damage.
How do you get a coyote out of a snare without killing it first? You will need a hog catcher type of rig, a snare on end of a pole like dog catchers use. You will need a roll of good duct tape, some gunny sacks and a whole lot of guts or very little common sense. A bit of both would help. You walk up to coyote that is caught in the snare, slip your hog catcher loop around coyote neck, press downward on pole as you work your way up to the struggling coyote. Once coyote is on the ground, run your open hand down his back, up over his head, on down his nose, and then clamp his mouth shut with one hand while you duct tape his mouth shut with the other hand. You then duct tape one front foot to one back foot so that coyote can't run away when you remove your snare. Now place coyote in gunny sack and tie the sack closed. The man who taught me this method gave the coyote shots for rabies, and a shot to calm him down. If you decide to try this, you will need a large holding pen made from hog panel, and you will have to keep your coyotes fed and watered until they are sold. Once again I must warn you to check your state laws before trying this.
