This is Duece the one faverolle mix for the year, his mom was a buff Easter Egger the color combo you mentioned is spot on though. Guy sends me updates on Duece and his faverolle brother Ray since he took them as a set.
I think you’d get pullets that were white with sort of faded black hackles kinda like a Delaware. And the beards & muffs would be lighter like an Easter egger. And then the cockerels would be similar but yellowish ..,again I think that’s what you’d get, I’m not an expert
I bet they’d be big goofy sweethearts in any case
