I did that in the primary for a week and then transferred it to the secondary with 1.5 pounds of pecans. Make sure you do a super rough chop on the pecans and roast them at 350 degrees for 15 minutes in the oven. I racked mine for two weeks and then force carbed it. Once you are done, you can use those pecans to make bread or muffins or whatever you think would go awesome with them. The beer had a pretty distinct pecan flavor, so if you want a less powerful pecan taste, one pound should be fine but I wouldn't do any less than that.
