BCM? or mixed?

I have a few photos of some chicks I bought from a farmer who wasn't entirely sure what they were but thought some might be BCM as they had a few of those chickens but couldn't be confident on that...what do you all think?

This one here we named Amber.

This one we've named lily (She doesn't seem to have any of the coppering that Amber has...though amber has in more area than just her neck)
