Re: As a horse breeder ...
Dammit Jake , you beat me to it.
Up until the end of the '90s I kept horses, I had two mares, one produced 5 foals and the other two before I quit owing to a divorce which made horse keeping unaffordable.
Normally there are physiological signs that tell you a mare 'might' foal within the next 24 hours, at that point I and all the other owners I have known, rearrange their time to keep an eye out. I can stand delivering foals, sheep, cows and kittens ( not that mares need much help) but I passed on attending my daughter's birth, the thought made me queasy.
