Observation of the development of chick embryo by shell-less hatching method.
This demonstration is practiced mainly based on the scientific article written by Tahara et. al. If you are scientist, you can reach it easily, because it is open accessed article.
The eggs sold in store are usually unfertilized egg and never develop to chick, hence you don't have to worry about eating embryo or baby chick. Now a days, fertilized egg is sold only in "organic" or "natural" store, family poultry farm etc.
The chick grows just same as normal chick.
