First Spatchcocked chicken

So I made my first spatchcocked last night and all I could think while eating it was "OMFG I cannot beilive that I cooked this!" It might be the best peice of chicken I have ever eaten. I was concerned while it was cooking because of all the smoke from what I am guessing is chicken fat but it didnt hurt it. see pic below, it bellowed thick smoke like this once I made the first flip (20 minutes) and didnt stop till done. I know it should be a very light clear smoke but all in all it tasted good
