This is what I do now:
regular calcium in the cage at all times
at each feeding I alternate dusting feeders with rep-cal calcium with D3 and rep-cal herptivite. The adults are fed every 3rd day. The babies are fed every day but I only supplement on the same days that I feed the adults.
This is where I'm heading:
dust at each feeding with calcium plus. I will be getting calcium plus and gradually transitioning from the rep-cal. I haven't decided yet whether I will be keeping plain calcium in the cage. I think I will since none of my geckos seems to be gobbling it up.
