the calcium i use is RepCal with vitamin D3 which can be purchased at many pet stores, including Petsmart & PetCo. If you have any reptile specialty stores around your area, they should sell them there too. IF you still can't find them on stores, you can order them online 
Then just pour some in a dish (i use a cleaned gatorade bottle cap) and leave it near your food or water dish. To coat your feeders, either place them in a bag and shake them up with the calcium inside or, do what i do - and that's just to put some calcium in the food dish, plop some feeders in it, cover it with your hand and just swirl it really fast in your hand
hehe~ don't forget to coat your feeders with supplements, i personally like to use Repitive. So not only do they get calcium, they get the essential vitamins they need.
