For those teachers out there who are weighing the pros and cons of an embryology unit, here is a thoughtful post on incubation.
Also check out my post about how I got started with chickens. An embryology project kicked off my love of chickens, and we did the “window on a chick” thing – cutting an opening in the eggshell to see it develop. This chick died, which made me very sad. If you choose to go the hatching route, you can see the blood vessel networking forming, the heart beating, and the chick developing with effective candling! No need for egg windows!
