I have two Silkies that are 14 weeks old and I am having a difficult time telling if they are pullets or roosters. At first I thought pullets, but they are stumping me now with their crests. The first 4 photos(same bird) its new crest hairs seem to be all around its crest. Comb is pretty flat and black and no waddle development yet. Do these look like streamers to you? The last 5 photos are of my other silkie that has me guessing. Mainly because of the newer feathers on the back of the head. No comb or waddle development yet.
