Hi, I am a first timer with 4 australorp chicks. They are only a week old, so I know I have a while before I can know for sure what sex my chicks are, but I was wondering what kind of things I could be looking for. I've read things about looking for how fast they feather, how thick their legs are or what color their comb is. But I am not sure which are just old wives' tales and which are reliable methods. Any help our guidance would be appreciated!
