Thank you for explainingSkunk are nocturnal. So it being out in the middle of a sunny day indicates it is ill.
While omnivores, skunks are scavengers by nature. They will steal eggs but don't normally mess with the chickens, although if very hungry they will. You should not see red blood on the face of a skunk unless it is a very unusual circumstance.
These things led me to believe it was rabid. It is just so out of character. And to attack a hen that could run away. Very unusual. Killing one on the roost is much easier. They are not really 'hunters".
