Candling eggs Day 7

It has been 7 days since I started incubating these 14 eggs and today I candled the eggs. 8 eggs are fertilised and are growing well and 6 eggs are not fertilized at all so I removed them. Out of the 8 fertile eggs all are alive. I can tell that because there are many veins visible like a net. I cold not see any blood ring which would mean a "quitter"

Non-fertilized egg is totally see through, no blood veins

Fertilized eggs have many blood veins
