I looked fried chicken up in my carb counter book and it seems that there is 16 to 21 carbs in each piece, depending on what you are eating.
The breading is the killer. There is no way to fry chicken with breading. Oil doesn't have any carbs so if you just fry it it will turn out cripsy, with no carbs. You are probably better off just baking the chicken, but it is whatever you like.
Take care,
