All 6 of mine have a dark wash at least on the legs and most on the feet as well. They all have at least a bit of dark wash on their beaks. At 4 weeks, I'm still pretty sure at least 2 are roos. I can't believe a sex linked breed is this confusing.
None of mine had spots or bars, still dont at about 4 weeks. That being said, 2 or 3 have larger combs, the start of wattle, and they spar A LOT. I'm not going to be happy if half of them are cockerels from a bin of sex linked pullets. Pics are when we first got them.
Then again, this year...
