I'm seriously considering buying 6 adult Narragansetts: 4 hens and 2 toms. They are between the ages of 2- 6. How long do turkeys live? Will they breed and sit at this age range? Will they fly away from my farm if I let them have access to the outside? I don't know if they will try to find their way back "home" to the previous owner since they weren't raised by me. What would you all do? Thanks for any help!
