It's fun to figure things out like that.
We had 3 d'uccles this spring. We had Ruby, and 2 porcelains. When I bought the porcelains, I thought they were bantam cochins. Then I noticed how they held their wings and tails. Hmmm... those cochins aren't cochins...One was a roo, and the other had a cross beak. Hers was pretty severe, and she didn't make it. She had the biggest personality! Your little lady seems to be managing well.
She is. It's more like she hit a brick wall and it sent her beak sideways a bit. She's the sweetest little chicken you would ever meet though.
