Phosphorous Deficiency

Phosphorous is necessary for healthy bones. If chickens receive a diet with an unbalanced calcium to phosphorous ratio it will negatively impact their ability to absorb both of these minerals. In young chicks, it will impact skeletal calcification and result in abnormal bone development, leading to rickets. In older birds it causes osteoporosis.
