I thought about buying a Standard From the UK, but it was more than I wanted to pay just for curiosity. I am not trying to be hard on anything. I just tend to speak matter of fact. I am not sure what the goal was when people imported Orpingtons into the US. They may not have wanted birds that met the UK standard, but were different than the US birds. If I am not mistaken, the Blues are heavier than the Blacks in the UK. Not sure why. Here, everything is the same within the breed, with varieties usually differing in only feather color. I have also noticed the Black Orpingtons in the UK are closer to their standard than the other varieties, but that is just from pictures, and my little understanding of their standard. I have Buff Orpingtons that are mostly Clevenger with some Farthing. I had a Cock that went about 15 lbs. I have one that is his offspring now that looks good at just under 6 months. I hatched some 100% English Buff Orpingtons last year, but was not impressed with them, in size or type.
