How long do you typicaly expect for a horse to settle in once you bring her home? I know its different among horses however I have read different rules of thumb on this issue. A new mare brought into a group of 2 other horses. How long should you expect it will take for her to settle in? I have a horse that has lots of potential under saddle but is very nervous since she has been here. approx 1 week. i dont want to keep her around if this is her personality. thanks.
