Guinea with black beak?

First post, so forgive me if I didn't do this right - This community is amazing and has helped us with SO much!
Quick question - has anyone ever seen a guinea with a black beak? Any idea what type this could be? We have two from the same hatch - very strange and haven't seen anything like it before, and their beaks have been black since they hatched.
TIA!
