What’s wrong with this bird?

Last month (July 2017) I photographed this Flemish Jay in the Ardennes. As you can see in the attached photo, this bird has a half bald head. Is this because it is still a juvenile or is it the other way around a consequence of old age? Or rather a disease or a victim of a predator attack or something else?

Presumably he was attacked, which resulted in him being partially scalped. Luckily for him, he had no further damage, was able to escape and survive.
