Duck claws not quite right, advice please?!

Hello, me again with another question! One of my little ducks looked a bit lame to me yesterday, so I picked her up to have a look and appears that one of her little claws is bent inwards, a bit like an ingrown toe nail.  Everything else on her foot and leg is fine and she's fine in every other way.  I'm just wondering if its possible to clip the claw with some tiny claw clippers, or is it best to leave it?  It looks like it could be what's making her a bit uncomfortable.
