You are going to get all kinds of responses to your question. There are so many ways to smoke a chicken or turkey. Brining, injecting, and putting on a rub. My suggestion would be to start with a broad breasted roasting chicken for your first try. I like to do them beer can style. If you feel like injecting it. I like melted butter, garlic powder, onion powder, & a little rub. Just inject enough to make the skin swell up. Then a little EVOO & your favorite rub on the outside. I also drink half the beer & put a little rub & some spices with the remaining beer. Smoker temp about 250. Take the breast temp to about 170 then wrap in foil & rest on counter for about 1/2 hour. Most roasters come with a pop-up timer in the breast. If you don't have a temp probe just wait until the pop-up pops. If your electric smoker happens to be a MES with the window in the door, just position the chicken so the pop-up is right in front of the window. Good luck & don't forget the Q-view.
