RE: Doe in estrus this early?
This is an unusual time of year where a few does will come into estrous early triggering a mini rut. I've witnessed it on occasion, but also have read alot about it. Most people don't know about it because unless you are in the right spot and out there everyday it is almost unnoticable. It doesn't last long either, maybe a few days. Most people that see this in their life figure it must be some freak coincidince, but it is very real. I think tazimna's encounter is proof enough. There is no way a doe will let a buck mount her unless shes ready.
Good luck with the estrous scent!
