My sister has just gotten a new pony, a lovely sweet 5 year old mare who has done very little except the odd hack. We aren't a novice family and have had horses before.
Pony has seemed edgy but okay since she came yesterday. She was lunged and turned into bucking bronco
and is very bargy and strong- excitement I think.
When would you think about getting on her realistically? Should we give her a week or so to settle or just try and get on board and hope what she did on the lunge she does not do ridden?!
Would a hack or school be better?
It's been a long time since a new horse came into the family and we are like a pair of novices again 
Thanks
