In all my years of breeding and showing Silkies I NEVER used a brush on one. I only used a hairdryer on low. It is too easy to injure pin feathers with a brush.
You have to be careful of course. The longer pin feathers it helps remove the shaft so the feather fluffs up and hides the smaller pin feathers. My birds love it even the house chicken which is by no means a show silkie. Most people would have culled her but I didn't. She was so sweet. She was still growing feathers here and there when her other brooder mates where outside roaming around and nearly ready to lay eggs. She's the sweetest one I have. She loves to cuddle. When it's bath time she thinks she's a duck and tries to dunk her head under. I always have to hold her head up. My splash roo turns to butter when I brush him.
YOu don't have to make the wires go down to the skin just rake over the top
