That's not unusual at all around here.
The most I ever saw together during the season was 11.
7 longbeards and 4 jakes all chasing around the same 3 hens.
Last year at the end of the season I shot an old bird with 1 3/8" spurs. There were 5 gobblers together around a single hen. All of them were big bearded birds, but I shot the one I did because he was the bully during a little scuffle they all had. When the dust cleared he was the only one left walking around cocky with a white head.......so he got dusted.
Couldn't tell you with any certainty how old the other birds were.
