From what I've seen in my neck of the woods, the button bucks get kicked away within that first year, before the rut starts. I say that for a couple of different reasons. 1)Earlier this year I watched a doe and her doe fawn trying hard to stay away from ( I assume) her button fawn that was bleating and chasing them. I don't speak dear very well but I swore his bleat sounded like "mom, why are you running away from me!". I kind of felt bad for the little guy. 2)Unfortunately I have shot a couple of button bucks in the past few years (good eating but not the way I'd like to do things on our land) and they have always been by themselves whereas the doe fawns are still with their moms. That's just my two cents worth.. very possible it varies state to state and doe to doe.
