Sexing 7 week old chicks - Black Copper Marans?

[nomadfromcincy]

We have 12 chicks that we sourced straight run from Alchemist Farm. I am going to post them separately so that any experts in each breed can provide guidance.

I am pretty sure these are 5 black copper marans. And also looks like we have some roosters.

Multiple photos of each and they are numbered 1-5.

Thanks!

Looks like a lot of Cockrell there.. number 3 might be a pullet but I'm not sure.. maybe someone else will chime in?

#3 would go on my hope list, but the other four look like cockerels- hopefully you wanted at least a few around!

I agree- looking like #3 is a hen.... Maybe #2? The rest may be roos.

Here's a pic of my BCM hen from 7 weeks (also my profile photo)- she always had a bit more comb/waddles than my other BCM hen. If helpful, there's a bit more photo progression here for your reference: Post in thread 'Weekly Growth' https://www.backyardchickens.com/threads/weekly-growth.1573303/post-26725844

Best of luck! I'd love to order from Alchemist Farms for my next chick journey
