Does will remain in estrous for 24-36 hours. Once a buck finds a hot doe, he will stick with her, go where she goes, and breed her as many time as she will allow. Once she is no longer receptive, he is off to find another one...
Also, many times bucks will herd a hot doe into remote and isolated places not usually visited by other deer so they can have her all to themselves...
Either way, sounds like time to call in sick and hit the woods
