So here I am watching Netflix's Steak Revolution and finding it a pretty decent show. At 48 minutes this English guy is talking about a 16th century book he read about 7kg chickens. He mentions that he was able to raise a bird of such size. Huh?! I have turkeys (Narragansett hens) that don't get that big. Is this guy full of it? What breed would be that large?!
