Best advice I can give on how to sex a chicken is to wait until about four weeks. Roosters definitely walk different. I had twelve hatch this year and tried every piece of advice I could find on this site but it's never consistent. Closest thing besides the walk I found from a piece of advice is to make a loud bang and hens will duck and roosters will lift their heads and look around. Not very scientific and when there's more than a few it's very hard to keep track.
