Livery Yard herds

[Horsenohound]

I’m in my first month of horse ownership on a part DIY livery yard I’ve ridden at happily for a good while (other people’s horses) with good hacking. I’ve no experience of any other yard but things are sadly not going well and I’m looking for some outside perspective.
My new mare was put into a field with the resident laid-back mare and both got on well overnight. On day 2 the yard owner decided to try my horse in another paddock with the alpha mare, who has a history of cornering, kicking and injuring two previous horses. She chased mine repeatedly (but mine stayed out of the way as best she could).

The following day (2 days after arrival) after another uneventful night with only the laid-back mare, mine was put in the field with the whole mare herd of 3 other mares. Mine and the alpha mare now seemed fine, mutual grooming etc.
However then for apparently no reason, mine kicked the alpha mare injuring her leg (I immediately offered and will be paying her vet bills)

Mine has been segregated ever since. The YO insists this has never happened before and my mare is awful. My coach thinks she has an actively lovely temperament.

I’m at a loss what to do. I feel the YO really doesn’t want us there now but I only bought a horse knowing I’d have good support, which seems to have evaporated very quickly. I feel at a bit of a loss.

Do any of you experienced horse people have any suggestions?

It's still very early days.

For now I'd insist that your mare goes out with one or two other quiet horses or on her own. If she has hind shoes I'd pull them or turn her our in boots to reduce risks.

Mare needs time to settle-they're always a bit more hot and flighty at first!

We have flock of six. If a new one has joined they are in a paddock next to for a week and then released either directly into the group or one by one introduced. Things happen and you cannot ensure that a horse will never be kicked or bitten even when the group is very established. suggestion to remove back shoes for now is good. I would also insist that your horse is not alone. They need their group.

And as PP says it’s early days. They can take a while to settle.

You're very kind to offer to pay the other horse's vet bills - I don't think that's the norm when a horse gets kicked in the field. 🤷‍♀️

Definitely less damage if horse is not wearing back shoes. That's a good suggestion. Our thoroughbred got kicked by a horse not wearing back shoes and there was no damage except some broken skin where she left a "footprint".
