Which two methods can prevent bent legs and stargazing in a young eyas?

The correct answer involves both feeding whole birds or small mammals and supplementing the diet with essential vitamins.

Feeding young eyases a diet of whole prey ensures they receive complete nutrition, including crucial bones, feathers, and organs that contain vital nutrients necessary for their physical development. This approach helps to build strong bones and skeletal structure, which can prevent the occurrence of bent legs as the bird grows.

In addition to providing whole prey, supplementing the diet with vitamin D3, calcium, and phosphorus is critical for developing healthy bones. Vitamin D3 aids in the absorption of calcium, while phosphorus also plays an important role in maintaining strong bone structure. Without adequate levels of these nutrients, young birds may experience improper growth and development, leading to issues like stargazing and other developmental deformities.

Therefore, integrating both methods—feeding a complete diet of whole birds or small mammals and providing appropriate vitamin supplements—ensures that young eyases grow healthily and avoid physical deformities.
