That's a hen, but she doesn't look like an orpington cross, she looks like an Araucana or Americauna cross looking at her butt. She is a very pretty girl!
I am in the UK and we dont have many ameraucana, but I kow the lady has Orpingtons and possibly araucanas as I have a chicken from a blue egg that is definitely not a Legbar! I already have a Cream Legbar roo! julia
