When I bought my Cham last weekend the guy gave me HERPTIVITE & CALCIUM with VIT D. Told me to dust crickets and worms before I feed them to my Cham. After doing some research I have found that I should only dust 3 times a week? The directions on the products say to mix them? I've been putting my Cham out in the sunlight for a few hours each day and If he's taking the VIT D that's not good for him? And I've read all chams need natural sunlight. What works best?
