Why didn*t anyone tell me they move?!?!

I*m on day 7. I saw veins on day 4 and thought that was cool, but today I checked again, and the little embryos are moving around! One of the little buggers is actually dancing . I had no idea they moved around so much--even my husband thought it was neat (the first time he seemed impressed with my chicken obsession) and my 4 yo says we should keep the radio on for them so they can keep dancing. How sad that every school-aged child doesn*t get the opportunity to study egg development first-hand. Think I*ll go write my congressman to toss out those silly teach-to-the-test curriculums and get incubators back in to our classrooms!
