When studying the development of a chick embryo by opening up an egg every few days to observe its growth, two problems arise. The first is that every egg does not begin its development at the same time or proceed at the same rate. Second, the disposal of the embryo after it has been studied (especially after taking on the appearance of a mature chick) is awkward. The psychological impact upon the child in killing the poor little chick is difficult to assess and, for some students, may even destroy the educational objectives of the whole study.
