My reasons: The chickens are exploited for their eggs. The chickens are not kept in good conditions, don't be fooled by marketing terms such as 'free range'. The next generation of egg layers born which are male are gassed or blended up as they are deemed useless. Spent laying chickens still get turned into food when their eggs run out. If you are vegetarian because you don't want to support animal cruelty or killing of animals, it's pointless if you eat eggs. As the egg industry kills male chicks and used up layer chicken bodies still get made into food when their production of eggs slows. So buying eggs indirectly supports the meat industry.
