This is my first time incubating eggs and I am desperate for them to hatch!! I have 6 Serama eggs and 6 Belgium D'uccles. I have candled them every other day from day 4 but havent been able to see the veins that everyone talks about but I have seen the eggs getting darker and changing- Im so confused because I just dont know if I have healthy eggs that are going to hatch!! I do have 4 that I have put to one side in the incubator which I have ruled out but they havent had any signs of going off with the bad smells or exploding- Should I candle them? Can anyone give me some advice or anything to put my mind at rest?
