You should definitely check your local feed stores - I have had good luck with my mine (Blacksmiths Corner in Bellflower). I know someone who traveled from Sherman Oaks to Temecula for chicks, only to discover later they were available in her neighborhood! (Sorry, don't know where that was.) This place is not too close to Woodland Hills and I haven't tried it, but I heard it recommended on the radio (on Good Food on KCRW) a while back:
Wes's Pets and Feed
4424 N. Peck Rd.
El Monte, 91732
(626) 442-0781
P.S. My reply assumes Woodland Hills means Woodland Hills, CA...
