Are Buff Orpington's generally very large? Mine is (or seems to be) growing at some alarming rate (like you can see a major difference from morning to night of the same day) and she's (hopefully a SHE!) has so many feathers, like that awkward teen stage (but she's having her 2 week birthday today) or maybe it's the barred rock that is extra petite? But I don't think so....the Buff Orpington has BIG BIRD STOCKS of legs and BIG FOOT sized feet! sooo I guess my question is do BO's generally grow fast and big compared to the BR?
