Need help with gender please!

Need help with the gender of these chicks please, the top pic is a 6 week old Blue Copper Marans, the next two are 5 week old Chocolate Cuckoos Orps. Two of the three have suspicious looking combs, but I am staying optimistic!

The first chick is a cockerel, the second is a pullet, and I'm not sure about the last one.

Thats what I was afraid of but thank you so much for the second opinion! I'm hoping that the chick in the bottom pic turns out to be a hen.

1st one is definitely a cockerel, 2nd one is definitely a hen and I am thinking a cockerel at the bottom, but you cant be sure at this age... hope its a hen!
