I bought 3 Silkies. 1 of them was older than the other 2. I really thought she was a girl at first because she had a lot of feather development. All my other roosters had almost no feather development until they were about 4 wks old. I believe this little silkie is probably about 3 wks old. She's been standing quite straight up lately, but the thing that is really making me question if she is a cockerel, is the fact that I believe she/he is already getting some waddle development. I do know that Silkies r harder to sex than other breeds. Just want to know, am I just paranoid because everytime I get chicks from tractor supply I always end up with a few roosters, or am I really on to something. Here is the chick in question. Is this waddle development I'm seeing?
