Generally, you should be able to start to determine gender in poultry at or
    around 12 weeks or so, sometimes earlier. See the photos below for some
    visual clues on gender.

    A good way to try to determine males from females is to look for saddle
    feathers. Hold a bird with the head facing you, looking down on it so you
    can see its back. When you look at the feathers just in front of the tail,
    which are called the saddle feathers, are they pointy, or rounded?

    Pointy saddle feathers mean it's a male bird, or cockerel. Rounded saddle
    feathers mean it's a female bird, or pullet. Same thing with hackle feathers.

    As well, hackle and saddle feathers of males will be glossier than females,
    whose feathers will be more dull and less shiny.

    Also cockerels generally have thicker shanks, bigger redder combs, and are
    generally larger and heavier than pullets of the same age.

    Behavior can sometimes give clues as to gender as well. Cockerels tend to be
    pushier at the feed trough and waterers. This is part of why it's a good idea
    to determine gender early, and separate birds by gender into different pens,
    which allows the pullets access to food and water without them being
    shouldered aside by the cockerels.
