Betadine, chlorhexidine, bleach, provent-a-mite, athlete's foot powder (for stubborn mold spots on eggs), q-tips, gauze bandage, speculum set (for inspecting mouths), needle-less syringes, digital scale, snake hook, long forceps, tweezers, a roll of scotch tape, paper towels, a plastic bin with a lid and clamps (for soaking), sexing probes, small ziploc baggies...I think that's all.

That's a list of all the things I've needed to use over the years, and a few I've just heard suggested. (I've never had mold grow on living eggs, to date).
