ok Listen to this. I am a middle school science teacher in North Carolina, and one of my previous students (in high school now) went to the regional science fair. What is so special about that you ask? Well her project was on hatching times of chicken eggs. Again not so special right? Well to make a long story short, she placed several eggs in panty hose, and some not, and incubated together. All eggs were from same hen and everything. It was a plain old hovabator type incubator. After 15 days, she took the eggs out of the panty hose and continued as normal. This was done several times, and low and behold, the eggs that started out in the hose hatched a full day early (day 20) each time. Cool I thought. After the science fair, she did the experiment again and same results. It was also discovered that eggs that were, or had a slight crack in them, were not affected by the crack. Just thought I would share some cool things that our kids from our state is doing in school. Plus I wanted to brag about one of my former students. But how cool is that. Next time I have some eggs to incubate, I am going to try this for myself.
