Rickets in birds is primarily the result of a calcium deficiency because this mineral is essential for proper bone development and health. Calcium plays a critical role in maintaining bone density and strength. Without adequate calcium, young birds, in particular, can develop weak, soft bones that may bow or fracture easily, leading to the symptoms associated with rickets.

While other nutrients, such as vitamin D, are also important for calcium metabolism and absorption, the direct deficiency that causes rickets specifically relates to the lack of calcium itself. Ensuring that birds receive a diet rich in calcium, especially when they are growing or during breeding, is crucial to prevent this condition.

Other deficiencies mentioned, like protein, vitamin A, and iron, may affect birds’ health, but they do not directly lead to rickets. Protein is necessary for overall growth and maintenance, vitamin A is essential for vision and immune function, and iron is critical for blood health. However, none of these are the primary cause of rickets in avian species.
