Carcass yield for BBB

[LeadHead]

We have raised our first turkeys this year, a couple of BBB toms. My question is what is the percentage for carcass weight that we should expect? When I weighed the boys just over a week ago they were 54 and 57 lbs. I know they will be the hugest ones we've ever roasted, but am not sure how much loss to expect after they're butchered.
Also, any tips on cooking time and temperature for such an enormous bird?

expect to lose about 10lbs on that size bird, maybe 15lbs what with the feet, head, guts and feathers. Its gonna take a big oven.

Thanks, Jason. We're thinking of roasting it in a pit like you would cook a hog. Another option we're considering is to make a smoker out of a 55 gallon barrel. Looking for helpful suggestions at this time.

poultry usually dress out at 70-80%.

cooking... the same as you would any other turkey.. only in a larger pan.
