Curb Chain to prevent bucking?
My husband and I are taking a percheron on trial for a couple of weeks. I learned yesterday that his current owner uses a curb chain so that "he can't get his head low enough to buck." I've NEVER heard of a chain being used this way (I grant it was my brother's horse that bucked, mine was too lazy), is this a common thing? I've always been told to close my fingers on the reins to prevent the horse dropping his head. (I should clarify I don't know yet if the chain is used properly or improperly with a snaffle bit)
I've never used a curb chain but I think my balance is good enough that I stay off the reins and could use one.
We are taking this horse to try him out for my hubby, and DH is, despite his years of riding, a beginner and certainly shouldn't be using a curb chain.
He arrives the end of next week and I get three hubby-less days with him to sort out if hubby gets to try him at all. Any suggestions on other bit/tack I could try that would be beginner appropriate. I'm probably going to have to ride this guy bareback (he's 18 hands, ~2500 lbs) until we decide so if he really bucks, not just a "I'm not happy kick" I'm probably coming off (buy stock in Aleve). Can anybody suggest how I can quickly find those buttons and push, I'm used to have more time to evaluate and find the buttons.
He is a great driving horse and supposed to be a good saddle horse I'm just nervous that he's been ridden in inappropriate tack and that I have a very short time to evaluate him.
