Bachelor groups are a tricky thing to try to figure out. I'm not sure when your season starts but there is a chance the bucks could hold their group and pattern till season starts. If the group breaks up usually at least one of the bucks will somewhat keep this pattern. Also if you are trying to get more information on the area and only have the one camera use the best observation tool you have, your eyes. Get out somewhere that you can see the field and the entry ways in, make sure you won't disturb the deer where you're at and make sure to be as scent conscious as when you hunt. Take some binos or a spotting scope with you and you can learn a lot this way
