I smoke whole birds including turkeys in my Big Green Egg. When doing a whole bird - breasts get to temp much quicker so you can put ice packs on the breasts before you cook to try and get all parts to hit ~160 degrees at the same time. I don't turn it at all, I use a Sittin Turkey/Chicken ceramic holder to keep the bird upright and moist from the liquid inside.

You probably don't have room in your oven to do a turkey upright but it works well on a grill and you can easily do a whole chicken upright in the oven. You can pour beer or other liquid and spices into the center of it to keep it moist. It's just a better beer can chicken. Highly recommend.

Good suggestion on turning in oven though if you aren't upright - less is more. Same with steaks and burgers.
