Hi all. My Silkies just aren't feathering right. Their top knots have feather shafts on most of the feathers, even though the shafts are in pieces. Should I comb the broken ones out? They still wrap around the feather but are not attached at the base. Also, my silkies wing feathers are scruffy looking. Some places have the main shaft but no strands along the sides. This is especially worse at the tip of some feathers. My Silkies are 14 weeks old. Are they normally scruffy and not fully fledged at 14 weeks? My other breeds are georgeous and fully feathered. Only the silkies are having feather issues, so i wondered if it was the breed. I'd give them vitamins, but I can't find any liquid ones locally. Where can order them?
