Sorry- I didn't understand what you meant above.
The photo of the last rooster is from a Speckled Sussex hen- is that black based?
Cuckoo marans and orpington are birchen based?
ok, thanks that is very helpful information.
Below are photos are my other non- black roosters.
I'm not a big fan of barring either. (at least not on black)
Am I right to think that my black based roosters are : my lavender orpington, 2 BC Marans, 2 cuckoo marans?
What would I get if I crossed a Lavender Orpington rooster and a CLB hen ?
What would the chicken look like?
What would I get if I crossed the same rooster with a Wheaton hen?
