I have 6 silkie chicks that will be 3 weeks old monday. All of the chicks but 2 have LOTS and I mean Lots of leg feathering. 2 have some down the legs but not much that id like to see on the legs. Looks like just small feathering down the legs they are filling out perfect in there lil white coats. Could it be that these 2 chicks will have less leg feathering then the others?
