And the chance of you being able to tell if the doe is in heat or not is slim to none.
Slayer, I disagree with you about being able to tell when a doe is in heat. When they lift their tail, stick it straight out, flick it constantly, and squat and pee every 2 minutes with their butt 1/2 inch off the ground, they're in heat. Pretty easy to distinguish if you ask me.
