99% of all eggs and chicks come from hatcheries, and they are no better than puppy mills. The parents and grandparents are bred and the less desirable offspring are killed in order to control the bloodlines. They are de-beaked and kept in sheds until their time is up. The fertilized eggs are artificially incubated, the chicks never meet their mothers, and they are inhumanely shipped via mail (not all make it alive to destination). In fact hatcheries are even worse than puppy mills because they kill the boys just after hatching (because not enough people want or can keep roosters).
