2 parts trace mineral, 1 part regular salt, 1 part di-cal, 1 part dried molasses, 1 part rice bran. Put three of these out 2 weeks ago and have pics on one site already. Moved camera to second site this past weekend. Third site is hit hard already. This is in a new area and I'm thinking that no one has any mineral licks out in the area. Also added some big box store cool-aid mix.
