the big ones just do the same thing they just cook a lot longer

I actually just started cooking fried chicken so I'm a begginer to but if your cooking the little ones (party wings) like I have in the picture ... get you a bowl get about 8 lil wings season them really good with your favorite seasons then add your flower make sure u put a lot of flower to you chickn i completely covered tgake your hand and toss heat up your skillet on high for about 4/5 minits are until hot put your chicken in and cook on each side keep turning until there is no blood coming out stick your fork in them to make sure all the blood is gone and keep turning until there krispy @mrs.aceves

silly question but I love cooking & everytime literally I've tried making fried chicken its never cooked all the way inside. can u give me some pointers on what I could be doing wrong? is the heat up too high? how would I know its done inside without having to cut it open?
