I just candled my eggs that my cochin bantum is sitting on. I have all kinds of eggs under her, 2 bantum, 2 EE's, 3 Marans, non of them are her eggs because I dont have a roo. I could only see through the shell of one bantum egg and saw little veins and a black spot. Hurray for me! Question, how do you see through those darker colored shells? (only day six, did I candle too early?) Help appreciated.
