i have to agree that most twins are one of each. this year in ohio i have seen 4 sets of twins that were both bucks but this is very unusual in my opion. i have also see several other twins with one of each. another observation i have seen this year is, i haravested a doe the first day of bow and she had two twin bucks. i have see what i think is both yearlings since and they have split up. but i have also seen a button and a young doe together several times they dont have a mature doe with them but they are together every time i see them. i think that this late in the year both sets of twins will make it except if they are taken by another hunter. they are mature enough that i dont think any other preditor will get them.
