Hi SurfCityBunpkin! Welcome! I'm new here too. I lurked for a long time doing all sorts of chicken research before I joined.
I'm in NOC too. In La Habra, pretty much right at the Fullerton border. My bf and I are still trying to finish building our coop. Hopefully there will be a erected roof tomorrow morning. Our chicks are getting big quickly.
I think chicken picking is fun and a very difficult personal choice. I mean, how can you choose when there are so many good options? Right now I have 4, which I got a the Yorba Linda Feed Store and Kruse's in La Habra. I get organic feed from Modesto Milling (the starter/grower crumbles) from Kruse's. However, I just learned of a store in Bellfower that sells Scratch & Peck, which is more appealing to me because it's whole grains and not processed crumbles or pellets.
As for chicks, I don't think you can really go wrong. The HB climate is so mild that you don't have to worry about heat or cold tolerance. I'm more inland, so we sometimes can get week-long heat waves in the high 90s or even low 100s in extreme cases, so I kept that in mind for my chickens and my coop. I have 1 barred rock, 1 Australorp and 2 Easter Eggers. They all are friendly, social, docile and have great personalities. I chose them for their egg-laying ability, looks and that they're less broody. My barred rock is really funny and makes a running beeline to me whenever I go outside. (They free range most of the day.) My Australorp is the runt of the group, but she's the most affectionate, sweetest and she's always eating. One of my Easter Eggers was the biggest cuddle bug, second to the Australorp, when she was younger. Right now, she's going through her prepubescent growing pains and doesn't want to be held, but she's still quite friendly and tame. The other EE was more skittish as a smaller chick and less affectionate, but in the last 2 weeks, she's been seeking attention more and even fell asleep in my lap! I didn't it'd be possible to have that with this particular chicken. It's been really fun watching them grow and their personalities develop.
My coop isn't even done yet and I'm already thinking I want at least 2 more chickens, but I'm having trouble narrowing the breeds I want down to just 2! I'm debating between Silky, Faverolle, Laced Wyandotte, Sussex, Polish or Hamburg. Eep. I hope my neighbors don't get mad or notice too much!
WELL HOWDY NEIGHBOR!
I live down the hill from ya in Hacienda Heights! Chickens are the BOMB and we all are glad you got hooked. Just so you know, we get together for fun chicken meet-up days 2X's a year, and the next one will be in Oct. after the heats gone....



.just in the summer months when it is too FRIGGIN hot to move!
