Does anyone know if there are any telltale signs that determine what sex Barred Rocks are? Today I've suddenly become paranoid about my supposed pullet being a rooster. "Kung Pao" aka KP, arrived around the same time as my other chicks at the feed store where I got them last week but is noticeably larger than the rest. KP has a white patch on its head and a blackish/dark grey wash on his/her legs and the comb is pretty pronounced, even at about a week old. Do you think its a rooster???
