After candling our eggs a 2nd time and seeing baby chicken embryo movement, we have 14 eggs left that are still developing. That is a 50% mortality rate, but one that I was expecting. Before I began this process, I researched and found that most "chicken-hobbyists" who incubated at home see half their eggs fail.
We started with 27 eggs, after 2 weeks we still have 14 growing. I am hoping that by Monday we will still have that many hatch, but I suspect not. I'm keeping my fingers crossed that 5 baby chicks make the hatch process.
Here is a video of some chick movement. I'm holding the egg, my son is holding the camera.
Here is a video of an egg that did NOT make it to day 12.
