My horses are all different.
Apache loves bread and carrots but wont even touch an apple. He loves the horse treats from the tack store as well.
Pepper is obsessed with apples and pears. She will it bread and carrots but isn't that keen on them.
Sammy will eat just about anything he likes apple turnover with cream, bread, apples, anzac biscuits, horse treats from tack store, broccoli, pizza without toppings, hot chips, cheerios the cereal he will eat carrots but isn't all that keen on them. That's all I can think of all off the top of my head.
I'm curious what sort of mints do you feed your horses? Does it matter? I've wanted to see if they like them but wasn't sure what sort is best.
