This practice is cruel and vastly outdated in many ways.
There is nothing educational about animals, the environment or life cycles that can be found from practicing such 'projects' or 'experiments'.
Chickens have complex social bonds and 'pecking orders'. These types of 'projects' deny them a chance to develop their natural bonds and deprive them of natural beginnings, hence negating the natural observation of animals and respect for their lives.
