There has already been several posts on this topic, but it depends on wher e you are hunting and the buck to doe ratio. From what i understand, there tends to be what we refer to as a "second rut" whent there is an overpopulation of does and they dont all get bread the first time around. If they dont get bread then they will come into heat a second time. Also, some yearling does might not come into heat until later in the year. The best way to find out if/when you might have a second rut is to be in the tree stand.
