I just got through smoking the biggest bird I've done to date. I have tried to stay away from smoking anything over 20lbs to avoid any "rule" problems. But I agreed to smoke a bird for a graduation and they brought this monster to me. Thanks to Pellet for recommending spatchcocking. It worked very well. Like I said 26.45 lbs!! Said he thawed in the fridge for 3 days and I pulled ice out of the center. Spatchcocked. Injected and covered with bacon. 3 1/2 hours into the cook I hit 140. WSM running steady at 325. I opened it up at the 4 hour mark to put some ABT's on the top rack. (forgot to get pic's of those) I hit 165 at 5 3/4 hours let it go the full 6 hrs and pulled it off at 167. The legs fell off when i picked it up. He wanted it pulled so...we pulled it.
