Hello, I'm a total newbe silkie chicken owner. My question is that my silkies are 13 week (black one) and 10 weeks (buff one) and both still have the appearance of having feathers and not pure silkie fluff like the silkie chickens I see online. Do they eventually turn more fluffy looking or it more likely that I don't have pure silkies? I adore them regardless, but my kids wanted silkies because they look like they have silk fur instead of feathers and mine don't have that appearance/feel and the shafts are still very noticeable in the feathers. Thanks for any info you can offer.
