My Cortunix eggs have been in for 12 days. Some of them I am getting a green clear glow through them. And some are dark and cant see through them. At 12 days They should be completely black right?? They are do to hatch in 5 days. So should i toss out the ones the candler light goes through?? I just had a 12 for 12 hatch last month, but I think by this time I checked them and they were black inside. Thanks Dave
