Hello! I recently bought three young silkies. Two are 16 weeks (gold and black) and one around 11 weeks (white). I know they are hard to sex so I tried to get the ones with the most pom pom hair do but looking at them this morning I am worried some are boys 
I'd love anyones opinion:
This is the younger white one:
This is one of the older ones:
And here is the black one:
and all three:
Thanks in advance!
