Abstract

Protein sources are highly diverse, with a significant portion coming from meat. According to 2023 statistics, there are 34.4 billion chickens worldwide, of which 8.3 billion are egg-laying. Many of these chickens are kept in small cages, but eggs, celebrated on World Egg Day, play a crucial role in nutrition and sustainability. This article explores important aspects of the life cycle of laying hens, focusing on their care and development.
