Skunks can and will kill your chickens. They are also a major carrier of rabies. Many years ago, my friend had a skunk get into a batch of kittens, killing some and fighting with the mama cat. A week or so later, they saw a skunk (presumably the same one) wandering around in circles in an old building. It was shot and taken in for testing. It was rabid. They were ordered to kill all of their cats and dog. They did, and brought one of the kittens from the earlier attack (their daughter's pet) in for testing. It, too, was rabid. The whole family (Kids were in 4th and 1st grades, and the youngest not in kindergarten yet) had to go through the rabies vaccines. The kids are adults now and hate needles to this day. Any skunks seen around here die of lead poisoning.
