Battery cages are like houses for chickens to live in. Imagine that you have a big house with many rooms. Each one of these rooms is very small and has a small bed, a water bottle, and some food. The doors are made of metal and are always closed, keeping you inside the room all the time. That's how battery cages work.
Battery cages are tiny spaces where chickens live closely together to produce eggs. These cages are made of metal wires with tight spaces where the chickens cannot stretch their wings or move freely. The cages are stacked in rows and columns in big buildings, creating many levels from top to bottom.
The chickens are kept in these cages all their lives without access to fresh air, sunlight or the outside world. They only see other chickens in the same cage and the food and water bottles. They cannot move around or do anything other than lay eggs.
Many people think that battery cages are cruel and inhumane to chickens because they don't give them enough space and don't allow them to express natural behaviours, such as scratching, perching, and nesting. Moreover, the chickens are susceptible to injuries, diseases and stress due to overcrowding and lack of proper care.
As a result, some countries have banned the use of battery cages, and many food companies are moving towards more humane farming practices that provide better living conditions for the animals.
