As far as seeing them in a field.....I think thats a lot different than knowing they're running together. I dunno, though. We watched a bunch of 'em at Brandon's a couple weeks ago....and a the youngins came out first, together. Then later...what appeared to be an older deer or two appeared. While they shared the same field for a while.....they didn't arrive together, for sure.
From my experiences, this is the norm. I've seen as many as three different bachelor groups come out to feed in the same field. They came from different directions. At the end of the night just at dark, a huge, drop tined booner popped out. He jogged across the field, stopped at the edge of the woods and licked a branch and disappeared. All of the other bucks approached the licking branch, with tails tucked, to check it out. There was no doubt who was the boss.
This behavior may change depending on how close to velvet shedding the bucks are. I viewed this during the 2nd week of August. I don't scout fields until after the 10th of July. What happens before that, I don't know.
