I don't believe you can tell by looking at the track if you can say it is a buck or a doe. I also believe the bigger the deer the bigger the tracks, buck or doe. So you're going to tell me if you seen the track of cfdjay's big doe, that you would know the difference. This deer is a damn cow! And I just don't believe unless you see the deer you can call the track. I'm sure in the northern states or Canada where there's a lot of snow, and you see a single track which is following a bunch of other tracks, then yes I would say that's a buck following a doe in heat. Other than that I think it's just an old wives tale.
