Sexing 5 Week old chicks

[Smiller1090]

I am picking up 7 5 week old chicks on Thursday. They are a mix of Black Sex Links, Grey Wyandotte’s and Black Wyandotte’s. I get to pick the 7 I want out of 18 chicks total. They are 5 weeks old. Any tips on what to look for would be great! Thanks

In Black Sex-links, cockerels have a light spot on the head when hatched, but I don't know if you'll still be able to see it.

Wyandotte cockerels have deeper, more vivid feather color than the pullets.

On all five-week old cockerels, you should be able to see the beginnings of wattles, and they will be reddish. The combs may be more pigmented than the pullets, and may be yellow-orange to orange-red.
