To the OP-I move my guy about every 6 months, since I go home to Va in the winter...and back to NY in the summer. Over time, yes, he comes and goes to the same 2 barns, but last year he was at 5 total (I bought him and he moved to NY, trainers in NY back to Va, then back to NY this spring to a place with an indoor ntil the weather got nice, now at my friends, which is our "regular barn", even tho he had never been there. He is also only 6, and I am his 6th owner. I have to say-he steps off just like he has lived there for years every time, adjusts easily and barely gets a scrape in the pasture, which is unusual. But, I make sure that for the first couple of weeks at a minimum, I am there often so that I become the familiar thing, rather than his surroundings. I think it helps, and he always comes right over if he is out, and nickers if he is in, so I feel like it makes him know I have not taken him somewhere and deserted him.
To Coffeegod-if your BO is indeed a "frail old woman" and your horse needs major groundwork, I can understand why the BO is a little out of sorts. Hopefully she fully understood what you were bringing her prior to his arrival. I would guess he is a challenge for her to handle for sure. I really do not theink you can, even nicely, tell her to back off, since it is very MUCH her business, unless you do EVERYTHING for the horse. I do not agree with her worming him when she did, but what is done is done. I would concentrate on the groundwork so that she sees some progress and is more comfortable with him. I am adamant about that myself, and my first question in a new place is whether my guy(s) are being gentlemen. T
