I don’t think deer are “synching up” or merging estrous dates……It’s a numbers game just like the example I was giving with county “X” and it filling up with 5000 does…….Which 5000 females does it fill up with in what combination and who dominates one area or another moving forward??.....When you released those 15 does from Sumter Co was there already 500 present of another lineage that had a head start??.....That kinda stuff is what has caused the differences in my opinion…..The same thing is occurring in my area around Russell, Lee, and Barbour…..The does are just following the estrous dates of their mothers and grandmothers
