Hi! I really need help from all the experts. I have Giant Blue and Giant Black Cochins. I can't tell who is Roo or Pullet with the Blacks. Their body shape seems different to me and they all seem to have a comb and wattle. So I don't know if I have all Roo blacks or if some are Pullets. Please help me identify them! If it seems like I have duplicated, I probably have but that's because alot of them look exactly alike.
