lol, I research A LOT because I want to breed a mare one day but I have to decide whether I want her to be mine (my chestnut TB is atm looking like a nice candidate) or whether I want to lease a broodmare.
What if you hired a foaling alarm? They give you lots of false alarms, and some mares will foal standing up, but it gives you a better chance of being there for the birth and with mini's that's really important because they do have a MUCH higher complication rate than big horses :) otherwise you could board her somewhere to foal down, there are facilities that are dedicated to it.
Up to you of course, if/when I breed my mare will most certainly be foaling down on someone else's property. I have friends who are experienced breeders, and I'm a huge worry wart, so it's what's best for me. But your decision needs to be based on what's best for YOU and YOUR mare :)
