Help with sexing my 5 week olds?

[hayesfamily]

So we have 5 five week olds and though I have some suspicions I could use some help, this being the first time we've raised unsexed chicks.
here are some pi


chick one. Silver laced Wyandotte, pretty pink on top, thinking cockerel?

cs

Now here's why I start to get confused cuz this is our Sexlink and she's the reddest on top


Here's where I cross my fingers and think I'm deluding myself, this is our Cochin, chick 2, the only Cochin we have so nothing to compare to but thats a pretty big and pink right? say it's a girl please

heres a different view



Chick 3, Ameraucana, thinking girl?


Chick 4, another Ameraucana, much bigger than 3, in fact biggest of all chicks, but no sign of red on top..... big girl?



thanks in advance for any help

1st two pictures look like you have cockerels, the 3rd, 4th, and 5th pictures look like pullets. That's some good luck, actually ~

thank you. Is that even possible that the sex link is a cockerel? We picked one of the red babies so we'd have one guarantee girl, but yeah the top is pretty pink.

SLW, sexlink and cochin...roos.

EEs...pullets

The cochin is way too red and advanced in the comb and wattles to be a pullet.
