Birds' feet

["Ross Bagpipe Bags Pty. Ltd." <>]

I am processing some images of Gang-gang Cockatoos taken today,  and  
while checking sharpness, have noticed that one of the talons (is  
that correct, by the way as all the books seem to just cover  
feathers) is broken.  It seems to taper in from the edges to form a  
hole.  It made me wonder if this would adversely affect the bird -  
altering it's grip for example or causing pain like dental caries, or  
just be like a broken finger nail, and are they hollow, like cow  
horns?  Can anyone enlighten me please?
