yes they will kill chickens, usually durning the night ..they will eat eggs & baby chicks....they also can carry rabies, from what i have read ,chickens can not get rabies,not possitive on this & do not want to pass on wrong info...BUT..other pets can get rabies from skunks. they will dig ground looking for grubs & frogs..baby song birds. any food garbage, cat & dog food... i love seeing skunks and actually think they are cute, But i have had to shoot my share of them also...once a preditor finds food on your property it will keep returning for more free meals, until you have no more to feed them.
