I can only guess, because I haven't seen the bulls. If they were satellite bulls. They won't have any cows of their own. They want them, but will get run off by the herd bulls.
Plus, 5 weeks ago the rut was pretty much over. The herd bulls have bred, and gone off on their own. The cows have done the same.
The satellite bulls you saw are looking for romance, but won't find it.
To see what you're expecting. You need to hunt archery, muzzleloader, or at the latest 1st rifle seasons.
