At what age can you start sexing silkies? I have 3 that are 2 months old. 1 of them is alot bigger then the other 2. I ordered them from Ideal. Is it possible they sent me 2 bantams and 1 standard. Do they even have a standard silkie? Their combs look alot alike. 1 of them is bearded and has a really fluffy head while the others arent so much. Should I post pics? Thanks Krista
