I can't imagine I would know what to do with a 30#-35# turkey! I get a small one, like 12#-15# at most from a relatively local place. If I were to raise turkeys they would have to go young or be one of the smaller breeds .... and still maybe go young 
I didn't quite know what to do with that size either! But that was almost 50 yrs ago & I know better than to let them get that size now. Back then, I was "waiting" for the holiday to kill.

I'm not sure I would want to cook one that big either. However, we would for sure be able to find ways to use all that meat!
I would probably pressure can about ten jars of it, as well as 5 or so jars of turkey soup, make turkey jerky with some, make bone broth with the carcass, strain & can in pint jars, and then just freeze the rest. That much meat would go a LONG way for the two of us! 
Did you mean 15-18# range???
