Moving day is a stressful day for horse and owner. We've had to move Beau ourselves twice...but as an ex racehorse, he's moved much more than that. Even so, he doesn't like it and never "gets used" to being moved from his herd and pasture to a completely new pasture and enduring the quarantine period. Neither is he fond of fighting his way to the top of the herd heirarchy.....
When we first bought him, we moved him to a temporary farm because there were no openings at the farm we kept Epona at. On moving day, he was trailered (alone) to epona's farm and he was screaming and whinnying for his herd and kicking/pawing the trailer floor/wall the whole way....luckily, it was a short move. only about ten minutes away.
The second time we had to move him was 8 months later about a half an hour away...but this went easier as he was moving as epona went with him.
He took it all in stride. But we worried about epona. She was impossible to trailer load....I don't know how her original owner got her to the farm we bought her from, but he must have drugged her. Once her owner wanted to take her to a training clinic and tried to load her and she went ballistic, even the BO couldn't get her on the trailer. She went wild. The trip was cancelled, and no one ever tried to trailer her anywhere again. So....on moving day, we were worried we wouldnt be able to get her on the trailer at all....my son worked with her in the weeks leading up to the move, and even though she trusted and respected him, even he could only encourage her to put her two front hooves into the trailer... The BO said, for Epona, that was a miracle....Moving day came and beau was loaded first. She balked a bit when her turn came, but nothing major. She was loaded in less than five minutes.
I know some may disagree, but after the move, our vet and BO both told us to not grain Beau(Epona does not get grain) for a few days (forget how many) and then when we reintroduced the grain to start out small and increase it slowly...I do remember that we increased his grain per their specifications and he still had a minor colic episode that passed within an hour....but we were told to leave his grain amount where it was for a few days before increasing again due to his having had a mild bellyache.
Perhaps that is being overcautious to not grain immediately after a move, but I figured the vet was smarter than me, So i followed her instructions.
A boarder who moved shortly after I did, however, did NOT withhold grain on the day of the move or afterwards....and her horse had no problems whatsoever.
OP, i'd ask my vet if they reccomend witholding grain for a time after a move.....some do, some probably dont.
