I decided to get an organic turkey this year. I went with one from Earth Fare, but they get their turkeys from a local farm. They had a choice between a natural turkey and an organic turkey. The organic has all the same attributes as natural, but it is organic and free range.
I got a pamphlet when I reserved the turkey - it said that natural turkeys do not take as long to cook as the conventional ones. Good to know that before the 25th!
