Do any of these look like Orpingtons?

[Aslea]

I just put an ISO out for Orpington hens/pullets and someone commented pretty quickly with this photo of their birds. I'm used to the thick built English Orpingtons that I have three of. Are there other varieties? Because these don't look like purebred Orpingtons to me.

There are two strains of Orpingtons. The big original English Orpingtons and the "American" Orpingtons that the US hatcheries sell. These were bred from the English lines years and years and years ago for faster development, smaller frame, and higher egg production. These "American" Orpingtons have lost nearly all of the true English Orpington traits. The birds pictured would be considered "American" Orpingtons or sometimes called "Hatchery or Hatchery Quality" Orpingtons.
