Hi, welcome

. I'm from CA too, but it is such a large state that we'd need to know what part of CA you're talking about, unless you don't mind paying for shipping, then it wouldn't matter what state it was from

. Why not try looking at birdbreeders.com if you haven't already.
Hello! I am from Southern California and although I would prefer to look locally, I am willing to pay for shipping if need be.
I have looked on birdbreeders.com, but it looks like a lot of the breeders around my area don't have Indian Ringnecks currently or are selling breeding pairs. I'll look more thoroughly/deeper into the site though.
Another SoCal local

. Although SoCal is still very large lol... if you want a baby, and don't mind driving a ways depending on where you are, Omar's Exotic Birds regularly has IRNs. In fact, on more than one occasion, I have seen some rare color mutations there.
OMAR'S Exotic Birds :: Babies in Our Stores I think they keep their website pretty up to date. This shows some IRN babies currently available and at which one of their stores it's at.
I've bought from their stores before, and Omar breeds a lot of his own (not sure about IRN) but I am very impressed with how they do things from weaning to selling.
