I am new to mini's, but not new to horses(daughter showed quarter horses and I showed jumpers growing up). I just brought 2 yearling colts and would like to know what feed to use. I have been useing a 10% all grain sweet feed with my 4 year old mini gelding that I drive and he did well with it, but he now will sift out the corn and not eat the corn. I've been told that it's not good to feed sweet feed to minis as it has too much fat. Right now they are on a mixture of half 10% all grain sweet feed and half 16% foal pellets. What should I be feeding my minis? I know if I change them to a new feed to do it slowly. I just want to feed them correctly. Thanks
