This is a discussion on Clyde Cross - but with what? within the Horse Breeds forums, part of the Keeping and Caring for Horses category; Probably your typical tb cross or soemthing similar to it....
He could be crossed with Thoroughbred or Quarter Horse. But with all the feathers I would guess a lighter draft breed.Depending on his height. Also it would depend on his bone structure! He could be part Percheron! Good Luck!
