Yes he was, you just didn't recognise them as such.
'Won't canter in one direction', 'won't take a certain lead' are generally symptoms of physical problems.
Anyway, is this normal for such a young horse to have so much wrong. .... Also, in about a month I have a rodeo coming up that I was going to enter him in for barrel racing,
Did you not ask the chiro these questions? Yes, it is as common for horses as it is for people to 'put something out' when playing or exercising, particularly if it's hard/athletic maneuvers.
Particularly if they're immature & doing high impact & athletic stuff, such as tight circles & fast paces, it is common for horses to suffer often permanent damage. Horses' lower spine/pelvis & hocks don't 'close' until around 6-7yo. For that reason, I would not be cantering tight circles, let alone barrel racing, on a 5yo.
