Second on the pictures. I have a SH cockrel who has weird feathers - they aren't silked or frizzled, just.... Not smooth at all lol
That's him in the background. Sorry for bad pic
Either their lineage wasn't carefully managed for strong fibromelanistic traits or they were cross-bred to a black feathered chicken somewhere back in the line. they look like SVs in the face, though, so we can only guess.
