sexing orpingtons

[christinew88]

Have three 3week old chicks, 2 Silver Laced Orpingtons and 1 Splash orpington. How soon will i be able to sex them and what signs am i looking for.
Uploaded some pictures but they are not very good as the chicks were moving quickly and i have a poor quality camera.

wait till about 6 weeks. the cockerels will probably have bigger redder combs and wattles than the pullets

cockerals also usually feather in slower than pullets.
the rooster's pointed saddle(back) and hackle(neck) feathers don't grow in until they are 3-4 months old.
