CCL sexing and maybe breed?

[The Moonshiner]

IDK
I wouldn't look at it as simply a recessive gene in the mix.
Those last chicks aren't just a gene off. They're way off.
I'd say something else was mixed into those. Maybe a stray rooster or maybe a different breed a generation or two back.

Thanks, I figured as much. They just seem too way off, I’ll see what they turn into will update later
Thanks
