Sexing Cochin and Cochin mix chicks?

[nursebecky99]

approximately when can I begin to get a better idea of sex on my chicks? I have Cochin roosters and ameracauna, red sex links (that were sold as RIR), Cochin, SLW and barred rock hens.
My 16 chicks range from 5days, 2 weeks and 6 weeks old.

Pretty sure at least 2/3 of the oldest are cockerels from an earlier post. But no clue on any of the younger batch. And darn they move quick to take pics!

6 weeks is about the youngest, 8 weeks is better. Post individual and preferably numbered pictures of you oldest chicks.

Okay I will as soon as the phone is recharged. My tablet takes the worst pics ever! Top and side view pics best?

Chick #3, aka Roger, has the reddest and biggest comb.

Chick #2 has a much more yellow/pink comb. They are all 6 weeks old.
