Why I dyed the eggs, well because my father-law and I had put a combination of both our eggss in our bator and there where two perticular eggs that I knew where mine and wanted to keep. They where supose to hatch tonite or tomorrow while I'm on vacation, and that was the only way to identify those two. Plus he don't know that I did that so I should be getting a hilarious phone call this afternoon. They started hatching 36 hours earliier than expected. But none of my blue ones hatched before I left, and u just twist a drill bit between your fingers about 1/2in from center of small end of egg and carefully with a seringe Inject 1/2cc of food color and seal hole with perifin wax.
