English orpingtons

[Chickies2020]

I just bought two 6 month old english orpingtons (one blue and one black splash) and holy cow theyre HUGE next to my 1-2 year old buff orpingtons. Are english larger by standard?

My Black English Orpington hen is pretty big and hefty.

I wonder why my buffs are so small by comparison? I have lots of other breeds (wyandottes, barred rock, rhode island red, faverolles, easter eggers, and brahmas). The brahmas are a little bigger than the buff orpingsons but the English orpingtons are GIANTS next to all of them!
