I agree to just sit tight until the Newcastle threat is resolved. Yes the restricted area is 50 miles away but that's nothing in terms of bird migration. LAX is part of the restricted area so no chicks can be shipped in either. Feed stores will not have any chicks until this passes. Later on if you can't find the breeds you want, order an assortment of 25 and sell the extras on CL. You won't have any trouble selling them especially if you grow them to 5-6 weeks and get them off heat. Lots of people are having to postpone chicks.
Knowing that area quite well, I can't recall there ever being a sizable breeder anywhere around there.
