I set 25 Welsummer eggs on 3/10, today is day 8. I tried to candle the eggs tonight, but I can't tell what Im seeing. I can see a darker area in some eggs, I see no veining. In only 2 eggs I can see a dark spot floating around & moving (kinda weird!) Is it common to not see veining in these dark shelled eggs???? Please tell me these are not a bunch of dud eggs! I drove almost 6 hrs to get them!! Any one have experience w/ Welsummer eggs???
