These birds are a combination of recessive and dominant pied. In the best case the bird is totaly free of melanin(black pigment) in all body parts. Very often there are parts unaffected. For instance a black toe, a green spot around the eye(s). In the case of your bird the beak is unaffected.
A pairing with another BEC can result in youngster with a few unaffected bodyparts to 100% pieds.
