RE: tracks in the mud?
In general, no. If there is a Deer processor in your area, go into the cooler with a tape measure and check the relative size differences between the does and bucks and the weights of the same deer. There is very little difference in the physical size of an adult deer regardless of the weight. As for the size of a track based on the weight, unless you have "calibrated" eyeballs, the difference between the depth of a track of a 185# buck and a 150# doe in the same soil conditions is indistinguishable. There are exceptions to all rules and a truly huge Buck will without doubt have a larger (deeper) track than the average Doe, but on the other hand his track will also be larger than the average Buck so consider what you are trying to achieve. Soil conditions, weather conditions and the speed at which the animal was moving will change the appearance of the track to the point where it is impossible to make a distinction. Rely more on the location of the track and the proximity of other sign than the size to determine the sex.
