one thing zarula, there is nowhere enough calcium in cgd to bring a deficent gecko up to speed. i almost killed one of my females that way after she laid some eggs. she got real rough, no rear leg movment, twitching, etc. if its real low on calcium, which the rear legs suggest, add more calcium. when the motion starts back up in the legs, then its ok to use just the powder. id also reccomend it to anyone breeding them, especially when the end of egg laying comes up and their stores are gone.
