One characteristic to look for when determining whether a goat is a billy or nanny is the typically stained/dirty section of hair on the rear haunches. This situation is generally created by the rut activities such as digging of beds/scenting locations and the profuse urination that it accompanies. Occasionally nannies will have some staining too but it’s typically more prevalent with billies. 🎥: @gabe_meez #dirtybilly #prerut #markingterritory #goatalliance | Rocky Mountain Goat Alliance

Rut is quickly coming to an end around here. It’ll be quiet and not so stinky for a few months. | Goats Gone Grazing Acres, LLC
