all hard to say...
ive seen a VERY mature buck running with a young buck during the peak breeding period AFTER our seeking/chasing phase...
typically, id say the dominant buck of the area aughta run the others off here reallll quick...im starting to see rubs popping up pretty quick and heavy...but its nature...never can say...and once the seeking/chasing starts they could all be gone...just never know...thats why i like hunting known funnels and pinch points that deer naturally travel through and not worry about what deer are where or anything...just gotta hope im there when a shooter comes through...
