I have four silkies. They all are very friendly and when i pet them, they let me. Except 1 of them are kinda scared but still pretty friendly. He/She has a sorta redish purple comb but its not much of a comb because it is flat. They are all 18 weeks and a half. No sign of crowing/laying yet. So far i think only 1 is a roo or maybe all is hen. I am not sure though. Hopefully i ll get some pictures taken today so you guys can help me sex it.
