Being new to the goat world, I am wondering if my 1 3/4 year old fainter is in heat. For the last 1 1/2 days she is much more vocal, and makes some really odd noises. She is also more affectionate; she wants to be rubbed much more than usual. She has no tenderness on any part of her body, fecal looks good, eats well and plays with her little sister. Her tail is upright, and the hairless side is pink in color. Does this sound like she is in heat? How long does this last and how often do they go through it? Any specific time periods in the year that they go in heat?
