Ducklings...in progress

Today, we "candled" the duck eggs with the blue group. Candling refers to shining a bright light into the egg and hopefully, being able to see the developing embryo. Each student got a chance to join a few classmates in a very dark room, and use the flashlight. We  saw many veins and lots of movement inside many of the eggs. 
Here is how we candle the egg, however, the lights must be turned off!

At one point, we found some eggs that weren't fertile. The eggs were very plain, and there were no veins visible. I explained that this egg was not going to develop into a duckling. The kids asked me why this had happened. I explained that there were many reasons and mommy duck maybe didn't lay the egg at the right time. One girl piped up "Maybe the mommy and the daddy duck weren't married!"
The eggs are set to hatch around June 10th. Stay posted.
