It doesn't sound odd at all, it sounds like barbecuing. You should always parboil chicken or ribs before putting them on the barbecue. So yes, I'm sure this does work.
No. I disagree completely. Parboiling removes way too much flavor. Cooking to the proper meat temperature, over the proper kind of fire arrangement will yeild perfect results every time, that is, juicy, tender, and done all the way through. I never par-boil any kind of meat before grilling/barbecuing.
And for fried chicken, there are a couple of techniques that will work well for you. First, instead of dredging in flour, egg-wash, sesoned flour, you can make a simple batter of seasoned flour, egg, and water. Completely dry the chicken pieces with a paper towel, and then dredge in the batter. You will have a wonderfully crispy coating that adheres perfectly. And for cooking, it is much easier to prehet the oven to 375' F., and fry the chicken until lightly browned. Then arrange the partially cooked chicken on a jelly-roll pan, and bake for 20 minutes. The chicken will come out so juicy that it will squirt you when you bite it, and be cooked all the way through.
Some alterations to the flour, egg-wash, seasoned-flour technique is to dry the chicken peices, brush with butter or oil, dredge in flour, then egg-wash, and then in either sesoned panko bread crumbs, seasoned bread crumbs, a combination of flour and cornmeal, or seasoned breadcrumbs mixed with flaked coconut. Then fry and bake as per the above instructions. All will allow you to get the best flavor and texture from your chicken.
Another interesting thing you can do is to make a cavity between the major breast muscle and the tenderloin (this is on bone-in chicken breasts), then stuff the cavity with a bread or rice stuffing, or with cheese, onion & herbs, or whatever you want. Then dredge in flour/egg-wash/breadcrumbs. Fry and bake as above. You can really get creative using this technique. Ham and swiss cheese are classic stuffing ingredients, as are garlic butter with herbs.
Hope this helps.
