Awesome!! this was regionals! 
Here's what my experiment was  
Hypothesis:
I believe that pre-incubation of hatching eggs has some truth and possibility. When I think about pre-incubation it makes sense that it could work. I think it will work because any eggs that were fertile would develop to a state in which they would remain fertile for a longer period of time than eggs that were not pre-incubated before starting the 21 day incubation.  The purpose of this experiment is to find out if hatching eggs that are pre-incubated stand a better chance to hatch than eggs that were not pre-incubated. If pre-incubation increases the odds of eggs hatching this would increase how people can ship hatching.   
Process :
I collected 3 days worth of eggs (about 18 eggs in total), I placed half of the eggs in the incubator that was set up and running for 3 hours to warm the eggs, to a state where they should be able to keep up to a month with out losing fertility. The other nine eggs were kept in plastic egg trays (where they were stored at ambient temperature for the three days). I did a dry hatch for this, I didnt put any water in the trough for incubation. I filled up the troughs about half way (there were two troughs) at day 18. I used an automatic turner so the eggs were turned every four hours.   
What I knew beforehand:
Before hand I knew that chicken eggs and some duck eggs are extremely hard to hatch,  I keep breeding pair or trio of the best, it is hard to get a lager amount of  eggs to set at once.  I thought that pre-incubation, would be a good idea on how I could store eggs until I had enough to make the incubator full .  There was a post on a discussion forum that I am a member on and this sparked my interest in this idea. From what I gathered there was a little bit of research done, but I was never able to find any.  
Materials:
~ 18 Chicken Eggs
~ One Hova-bator 1588 egg incubator
~  One Hova-bator automatic egg turner
~ ½ cup of water for hatching
The Results:
The final total hatch rate (for both groups) was  83.3%, this is the best hatch rate I have gotten. The hatch rates for control group was 77.8%  with 22.2%  not hatching, the hatch rate for the pre-incubated group was 88.9%.With 11% of the pre-incubated eggs not hatching. 
In the control group, there were two eggs that did not hatch. With the pre-incubated group 1 egg did not hatch. All eggs up until day 18 developed normally.
