I've seen ferrets from 6 months to 8 years old with a few webbed nails.
Some of the younger ones have one webbed nail, versus the older ones.
Never heard anything about what may cause this, any suggestions?  The few
ferrets I saw had the baby nail webbed.
 
Could a ferret be missing something in their diet to cause this?  Thanks
for any advise.
