You can use soy flour, or something I found, called Keto Crumbs, for frying. They are both low in carbs and provide a nice, crisp coating. I usually do not use egg, but just dredge the food items in the soy or crumbs to add a light dusting.

With either product, lower the flame just a little more than you would with a flour coating, as both of them tend to brown quicker.

As another person said, roasting/baking is a most tasty method of cooking chicken. I rub herbs up under the skin and roast the chicken on a rack so the juices drip away and the skin becomes crisp. I also roast it breast side down. The chicken breast always tends to dry out, but this position keeps it moist. You can also then use the drippings as the basis of a delicious sauce.

Obviously, do not eat KFC. The breading on it alone will put you into a huge carb surplus. I imagine you could peel off the breading but the temptation to not do so could prove overwhelming.

Good Luck!
