These are from my White Bresse they are 5 1/2 months old.
As you can see the whole feather pattern on the cockerel makes a smooth silkie cover from neck to tail.
While the pullet almost seems to have ruffled edges.
It took me a while to figure out who was what. That's why this cockerel's name is Molly!
