How do you tell the age of a sheep horn?
To age a bighorn sheep, look for the four year ring and then count the rings toward the skull from there. Once you are able to quickly identify the four year ring, aging rams becomes easier. You may notice that most of the time, the growth throughout the horns will be spaced differently.
