Are these male silkies?

[vansal]

My 13 week old silkies have developed wattles. My year old silkies do not have them. Is this difference of where I purchased chicks or are these males?

Are your first ones bearded? Usually bearded ones don't really get wattle development!

The one in the second pic has red wattles and comb, which most likely means that they came from a hatchery.
