What advantage(s) does raising an eyass provide?

Raising an eyass, which refers to a young hawk that has not yet fledged, provides several advantages that are crucial for falconry practice. One significant benefit is that it is relatively easy to man an eyass. This is because they are more adaptable and less set in their ways than older birds; their natural receptiveness allows handlers to acclimate them to human interaction and handling without the complications that can come with a more established bird.

In addition to ease of manning, raising an eyass allows for ample time to work with the bird. Because eyasses are raised from a young age, falconers have the opportunity to train them gradually, fostering skills, building trust, and creating a strong bond. This extended period of training and socialization is crucial in developing a bird that will perform well in the field.

While feeding an eyass is generally manageable as they are often quite accepting of provided food, the aspect of feeding is not deemed a major advantage when compared to the training benefits. Thus, the selection that encompasses the aspects of ease of manning and the ample time for working with the bird captures the key advantages associated with raising an eyass.
