Is it posible you have two BRs? I see my CM on the right in the second picture you posted. Otherwise, the markings on your two are much more distinct than what I have. My CM's are mostly dark with a few white accents (except for my roo, which is lighter but still doesn't have the distinct markings yours have). I see in your pix that you have two that have very pronounced markings, and one that doesn't. I'm wondering if you got 2 BRs and 1 CM - especially since your last pic appears to show a well-marked lighter bird with yellow legs - my CMs are mostly black with some markings and light colored, realy pale legs. If you look at the pix I posted, you'll see the pullet (looks like the 1 of yours) and the roo (pale like the 2 of yours but without the distinct markings).
Hoping that someone with more experience chimes in here - I only know what I've got in my henhouse and what I was told they were, but it doesn't add up with what PTFowl has and was told ... beautiful pullets, though!
