Yesterday I candled 2 eggs that were on day 12.
In one of them (black pekin), I could clearly see the embryo moving. The air sac and the veins were clearly seen also.
In the other (mixed bantam, slightly larger than the black pekin egg), I could clearly see the veins and the air sac, but half of the air sac was darker than the other half
. Is this normal? What's happened?
Many thanks in advance
