Feed one good time in the mornings. The feeders have to be "lightly" dusted with 3 kinds of supplements. Plain calcium (no d3) at just about every feeding...... if you skip one or two days a month that's ok. Calcium with d3 twice a month and a multi. vit. once a month. In this link I use the 13th, 15th and 17th one. http://lllreptile.com/store/catalog...d-cage-cleaners/reptile-calcium-and-vitamins/
