I have an 8-week old Speckled Sussex who's left outside toe is rotated 90 degress so the "claw" faces backwards instead of down. She eats, perches, flys and lands just fine. She's a sweetie and seems not even to notice. I'm leaving mine alone as she's happy, healthy and getting along fine and I'm guessing that yours will be o.k. as well. Good luck with her.
I also have a seven week old speckled susexx named Paprika and she seems to be getting around fine. I had my friend over today and she noticed the toe that was crooked to the side. It freaked me out and i just wanna know if it is a big problem that means i need to see a vet. She gets around fine but when i touch it softly she starts to squirm.
