Wow. Thats a new one! Looks like one of my EE's but with feathered legs. Maybe an EE/Cochin cross? I've never seen one, but thats my guess. What hatchery did you use?
Here's pics of my EE that looks very similar:
at Two Weeks:
and now at Four Weeks:
Maybe that helps? We'd actually name him/her ChickenDuck because we thought he looked like a baby mallard duck! lol
From what I can see it looks like a partridge. Mabey a cochin but it is a feather footed for sure. If it is a mixed breed you might be able to get an opinoin on it.
