I have had eggs in a tumbler for a few days now. I stripped them from a female that was holding for 3 days. All but one turned a dark color. One is still same shade white as when I stripped them. They are bouncing softly, and constant. I noticed today a couple small white spots on a couple. Are these due to development or is something wrong. Are the dark eggs bad or the one white egg bad. I figured either the one white egg was fertilized and the rest weren't, vice versa.
