I have 4 birds 2 rir's 1 blacksex and 1 ?? Im thinking one of the RIR's is a Rooster, my question though is about crowing.. All 4 of the chickens are real chatty, always making noise, but I noticed one is alot louder than the others.. It doest sound like crowing, or a typical cokadoodledoo its more like bawkbawkbawk, kinda similar sound as the other girls just alot louder. Im wondering if theres a way to tell if its a rooster by that or if i need to figure out how to get the pictures off my camera so you guys can see them. They are also 23 weeks and no eggs.
