Hi there! So here is my dilemma, I have two jet black horses and one black and white pinto horse. I turn them out in the morning until about 11 then turn them back out between 4 and 5, I don't want them out in the harsh part of the day because of the heat and the sun bleaching so they get pampered by staying inside under their fans My geldings (a black and the pinto) get flax seed and the mare (the other black) is going to be on flax but is currently on smart dark and handsome. The problem is that their flanks are sun bleached brown! I would expect the sun bleaching to be on the back? How do I get rid of the brown on their flanks?? Thank you!
