First Candling!

Today is day 7 and we get to candle!  


Hmmmmmm, I wonder if our little baby birds, called embryos, are starting to grow and develop?  How can we find out? We wouldn't want to crack open the shell would we?

No, no, no!  But if we could it might look something like this picture .


Candling is the name for shining a special bright light into the bottom of the egg inside of a dark room.  By candling our eggs we will be able to see the embryo, which will look like a dark spot, and some spider looking veins around it.  If there's just an outline of the yolk then no embryo is growing and developing.  Check out these pictures of our eggs from our first candling!




We made a chart to predict which eggs will continue growing and developing and will eventually hatch.  Winner, Winner, Chicken Dinner are eggs that we could easily see the growing embryo.  Quitters are eggs that we could only see the yolk so there is no embryo developing.  Yolkers are eggs that we think are growing but aren't totally sure of, sort of maybes!
