Is she sticking her head in the barn gate to get six inches closer to your buck, all the while twitching her tail like she is flagging down a cab?
Is she rolling around in the dirt moaning like a shameless hussy embarrassing females of all species with her utter lack of humility?
Is she urinating all over the barnyard with a Mae West, "Why don't you come up sometime 'n see me?" look about her?
Is she baaing relentlessly so loud that you are thinking of putting in ear plugs and hiding the basement with a pillow over your head just to have a few minutes of reprieve?
If you answered yes to any or, in our case, all of the above your goat is in heat.
