Back in the mid 90's, the Indiana spring season came in 5 days a head of us. One year, we killed a bird in Southern Indiana the first hour of the opener. By the time we got to a check station, there was a line out the door. That morning I watched a 31 and 33lb turkey get weighed on a certified scale...looked like f'n terradactiles. The first check in station in Ohio was at the Waterloo Wildlife Research Station in the Waterloo State Forrest. Over the 40+ years they weighed birds there, they never had one top 24 lbs.
A trophy gobbler is one with a full fan and a long beard. Ive had my feelings hurt by many a 2 year old. The heaviest birds are usually the 3 year olds and everything has to do with available food and agriculture. The birds we hunt in Ohio today are decedents of birds trapped in Missouri at the Mark Twain and relocated to SE Ohio. We traded them grouse for turkeys.
The older, (and in theory), wiser birds with 1.5"+ razer sharp spurs usually don't weigh all that much for the same reason a rutting buck doesn't...they spend their spring fighting and chasing tail.
