Weird double nail on Silkie

[ArtCaptain]

So I was petting my almost 2 month old Silkie when I noticed (i don't know if its a hen or a roo yet) its nail looked as if 2 nails had come out at the same time out of one toe.













So far the silkie seems fine...has anyone else had this happen to a chicken? should i be worried?(is this good luck or something?
