Still early for silkies, but if you want to have a go at the genders, please post individual photos of the birds with close up of the combs, crest pushed back with one hand if possible. Obvious boys will be evident, but may be too early for definitive pullets or later developers. 
Most silkies have to wait until 16 weeks of age or even longer with some birds.
