I posted this before but Im not sure if it was in the correct section or not. I have a 15 week old black Silkie that Im not sure if it is a male or female. I got a blue Silkie at the same time who is quite a bit bigger, has a larger mulberry colored comb and is crowing. The black Silkie hasn't crowed but has a decent size comb and a sort of swept back crest. He/she has almost no waddles. Any ideas?
