When a hen is ready to lay an egg, she will start to look for a safe place to do so. This is because, when she lays her egg, she will need to be able to sit on it until it hatches. If she is not in a safe place, she could be attacked by predators or other animals that would see her egg as a tasty treat. The most common places for hens to lay their eggs are in nesting boxes, on roosting perches, or in tree branches. All of these places provide the hen with a sense of safety and security, which is essential for her to be able to lay her egg successfully. Mother hens are incredibly protective of their eggs and will do everything they can to keep them safe. This is why it is important to provide them with a safe place to lay their eggs.
