Really??! I thought they only laid some crazy number like 50-75 eggs a year. Please forgive my numbness if this is waaay off. When I was growing up we only had the gigantic white meat ones and we almost never kept them much after Christmas. We would get over 100 turkeys every year so my dad wanted to try and see if we could breed them. So we did tried to keep them after a year old but we only ever got a few eggs and they were never fertile and the toms would have heart attacks because ours were always bigger than they were supposed to be getting upwards of 35-45 lbs. We even had a 52 pounder once that went to the soup kitchen in the next town over.
I think you had broad breasted in the past. Heritage turkeys breed naturally, broad breasted require artificial insemination. Turkeys however are not all year layers like chickens.
