OMG this thing is HUGE. Guess we went past the 18 week mark by a few months. I also let him free eat so he and his partner ate 50lbs per week. They were eating machines! Anyways......... I cannot find any info on extra large birds and cooking times. I am guessing 325f for 9-10 hours. I also made the mistake of bringing it for 4 days. I forgot about it when we had a massive wind storm and loss of power (its cold here so turkey is OK). Should I soak it in fresh water overnight to pull some of the salt out? Help..... On edit...... The bird turned out AWESOME!!!!! Best turkey I have ever eaten. We fed all the folks and had 15-20lbs left over. Brine was awesome and it cooked in 6.5hrs.
