we have been lucky both our colts last year (our first 2) were born at around 11:45 PM we were just getting to sleep but we are fortunate enough to have a camera with sound and my husband Art is a very light sleeper lucky for me.
But the camera and foal buzzer were the best investment we ever could have made.
So far i have just hit the button on the coffee on my way out to the barn.
But i can only imagine we will have harder nights
