On July 19th,2011 at 12am I set 16 Button Quail eggs.. I just candled 3 of them and one I couldnt see through (I guess the shell is too dark or thicker, there is about 3 like that, that I know of but you cant see the light come through..) and the other 2 where I have the "O" marked on the egg, there is a little red spot with veins branching off of it.. does this mean that the babies are growing?! at 3 days would you even be able to tell or is there something else going on? Please help me!!
