How do you tell if a baby chick is female or male?
If you have a "sex link" chick, it's easy! Males and females hatch out different colors. Red Stars are a very common sex link, and the females are a reddish-gold while the males are a buttery color. With "Black Stars", both males and females hatch out black, but males have a distinctive white spot on their head. If you DON'T have a sex link chick, it can be much harder to tell!
Our experts "vent sex." This means they look at tiny differences in the birds' vents. You would think there would just be two shapes, one for male and one for female, but there are actually 15 different shapes in chickens. It's definitely hard to tell the difference, but we guarantee 90% sexing accuracy on our baby chicks. My Pet Chicken is also the only place in the country that offers sexed bantams.
If you're trying to tell the difference at home or with chicks you've hatched, you may not have any luck for many weeks. Early signs can be a larger, redder comb and wattles, but some pullets mature faster than others and some roosters take longer to mature, so usually it is a waiting game! In some breeds, spurs are common in both sexes (bantams in particular), and in others only the rooster will have spurs. However, females will have bumps where the spurs would grow, and at a young age it is not possible to use these to tell the difference. In short, unless you have a sex-link breed, it's near impossible to tell until your bird produces a full-on crow (at about 5 months) and develops longer, pointier feathers on their tail and around their neck (at about three months)! Even more confusingly, hens will sometimes crow. See below for more information about that.
