1. it depends on how long the egg has been fertilyzed. we did an experiment back in grade school and it took a few weeks.
2. Chicken eggs take 21 days to hatch, once you start incubating them. They won't start to develop until incubation starts. Here's some more info. about incubating eggs. http://chickscope.beckman.uiuc.edu/resources/egg_to_chick/procedures.html
3. Under optimum incubation conditions , this will take 18 to 20 days.
4. 21 days
