Okay. My mare was due on the 7th of April. For her previous owner, she would generally foal a week before. But since its for me, she's not going to! But this is my first time foaling a mare out and I keep reading the signs and such, but not sure of myself. So here's what I got. Her tail bone has lifted and hips out. Her vulva hasn't changed colors yet. So here's some pics. Does anyone have an estimate as to how long she may be???
