Where can I get a White Silkie - ASAP

[Higgs2001]

Just bought 3 chicks from my feed store. Got all the breeds I wanted/researched, but they were sold out of the White Silkies. Hoping to get some in the next few days so it's not too late to integrate them into my "flock". I live in Pleasant Hill (East Bay) in California. Near San Francisco. Any suggestions?

Thank you so much for any advice/help!
