while i can see why one would not want to use it, if not given to much you will not run into any problems concerning vitamin d3 toxins
the D3 is what helps them absorbe calcium, giving them just straigt calcium is fine, but it would be much better to give them a feeding with d3 at least 2 times a week, it can be very beneficial to them
i use rep cal calcium in the mealie dishes, all week long, i skip feed on thursday, and offer mealworms dusted with calcium and d3 on saturday and sunday, then monday i go back to the calcium..i've had an amazing egg laying rate this way..not saying this is the best way, nor am i saying i disagree with you..this is just MHO
