I like to see my horses in a large good in a nice big field.
But after 12 years of serious injuries. Ripped rugs etc. I am moving to a different yard with smaller groups in smaller field.
It can work. But bring livery you won't ever get a perfect herd.
If you got to pick and choose who joined the herd according to how they get on then its likely to work most of the time. But even then you will still get occasional problems, the same as if your horse was out alone!
i would rather one other on an acre -too many accidents happen in large herds.-makes me very nervous,my horse doesnt like being out much anyway ,after an hour hes ready to come back in!
11 acres. Even for a good doer, its not that much more land per horse, but they'd have to do an awful lot more roaming & therefore exercise. Mine also is a true lead mare, & in 22yrs has never had any issues, no matter what groups she's been turned out with, even with horses who were known to be a pita. And she'd look after the other in any herd situation.
