Sexing 7 week old mix breed chicks.

[LULA Pottery]

Howdy. I've been on here a ton over the last couple years but finally just signed up to be able to ask my big gender question.

We brought some hatching eggs home from our vacation in Maui and now have seven chicks. They are 7 weeks old this week. All the chicks are mixes and have either an OE or RIR father.

Each of the seven is distinctive-
4 came from OE hens-very dark olive green eggs, so I know there is a lot of cross breeding (more like a free for all) in this crew.

Thank you in advance for turning your expert eyes on this crew. Pictures on the way. Hoping it works to post images separately since I have so many.

#7-
White and black chick has a SLW mother and we though RIR father, but where'd he get the muff? He seems the obvious roo. He has a huge frame compared to the others, and feet, chunky legs, white patches on shoulders and chest, a roundish tail, and check out that comb and wattle situation.

7 is a cockerel. Not sure about 3. The rest are pullets.

That's exactly where I am right now with them, @Keeperofmunchkins Thanks so much.
