I raised 3 turkeys this year, first time. Mrs Nut decided to do a practice run and roast a turkey today to try them before Thanksgiving. She cooked a 21 lb hen in a roaster at 325, same as she has for 33 years. The bird tasted okay but was VERY dry. She had water in the bottom, rubbed it with butter and basted it in between. Any special considerations cooking a home grown turkey needs, or did I just raise a bum bird?
