We bought sexed barred rock chicks from TSC and they are now four weeks old. I didn't bother to find out about sexing barred rock chicks beforehand but it seems there are several tell tale signs even when they are a day old that we didn't check. These traits are even more pronounced now: - his (I'll stick with the masculine pronoun) comb is more pronounced than his flock mates - he pecks at our hands when we try to pick him up - the white spot on his head is more diffuse - he has lighter legs - his feathering is lighter All are apparently tell-tale signs of a rooster. In case of any doubt here is some photographic evidence. The top one is "Pecky" and the bottom is, I assume, a pullet. She wasn't cooperative to show off her legs but they have dark markings down the front. So is this beyond all doubt a roo that we have?
