I'm not sure about nutrition wise (and seeing below I think the question was answered...) HOWEVER... I LOVE the dark meat! Give me skinless chicken legs any day!
FYI... when I was a kid my mom ALWAYS skinned the chicken (all parts) because my dad hated the look/feel/taste of skin. It wasn't until I was in my late 20's that I ever had a piece of chicken skin. It sort of creeped me out!
