Are you sure about the mom?
If so the sire was bearded and crested.. also clean legged and 4 toed.. not 5... because feathered legs and extra toes are likely to pass on.
I wonder what comb type that is.. on my screen it looks like a standard pea.
To me.. bearded Polish is a possibility. But I might be hard pressed to rule out some EE or other crosses in there.. not knowing the full set of details..
The cresting itself.. still in the juvenile phase looks more like CCL or Swedish Flower than Silkie or Polish.. but perhaps because of being crossed or maybe still coming in. And would not explain the beard.
Anyways.. despite not being real good at it.. this is still one of my favorite games.. I love a good mystery, thanks for the invite to participate!
(a lot of new breeds with small crest have also recently came on scene in the US, I'm not familiar with)
