Several years ago I read a study that showed that 5% of the Does breed as early as September, then the rut peaks in November then trails on out to Feb and March. Does that get missed during the main part of the rut will come back in, in 28 days, and continue to cycle until bread. About 60% of the doe fawns will breed before they are 12 months old, but typically will not come into estrous until later in the year. when they are 10 months or so old. so to answer your question, strange? No, Strange to witness? Yes, it happens, just not all that often, in comparison.
