Rule of thumb is 15 minutes per pound. So 9 pounds would be 2 hours and 15 minutes. At 2 hours, try to "shake hands" with the leg. If you are able to move it, the bird is done. Hope this helps.
Chip. Thank you for your answer. I never heard of "shaking hands" technique I'll have to try that on new years when my family will do Christmas day.
