just take it a mile away and let it go i get them in my barn and all they eat are the eggs i just let them go back outside no need to kill it if you dont have to.
never had a possum bother the chickens just eat a few eggs i just pick em up by there tail and let them go outside roadkill possum goes in the oven with some sweet potato.
