Hi I am after some advice on which hygain feed to give my horses. I have a laminitis prone miniature pony, a purebred arab gelding and a 8mth old miniature pony colt. I would like to feed them the same I am currently feeding them all hygain ice. I was wondering whether hygain ice is better for them than hygain zero. The arab is a bit of a porker and he can't have protein as it sends him nuts. Thanks in advance.
