Candling is used to see inside an egg without breaking it open. It allows us to see if the eggs are developing babies. To candle an egg, you need: a bright light, an egg, and a lot of patience. To candle the egg, we put a light under or behind an egg. The light shines through the shell, only a little, which lets us see veins, body parts, and the yolk. In the beginning, we may only see the yolk, but if we wait a few days, we can see some veins. After about a week, we will start to see the baby forming. We don't get to see details, but we can see a shadow. This entry has eggs that are about to hatch. This is an unfertilized egg. There is no baby inside. This is not all yolk! In the middle, you can see a darker area, and that is the yolk. We can't see any veins, even though this egg was under a hen for the past three weeks, so that means that it's not developing a baby. (All the dark stuff on the egg isn't inside. It's dirt, and maybe a little poopy from mom. This is perfectly normal.) These eggs are both fertile and are filled with babies! The egg on the left has a white shell and the egg on the right has a brown shell. At this stage, just before they hatch, the baby has nearly completely filled up the egg. That's why it's so dark! In the egg on the right, you can see a little air pocket. This is okay because it's small. If the air pocket was big, that would mean that the baby was dead because bacteria got inside (bacteria let off gasses that create air pockets inside eggs). We can tell that these eggs will probably hatch in a few days by how dark and full they are.
