Welcome to the Snowflake area. I live 30 miles north of Saint Johns. I don't think you will have any problems selling your eggs for $3 a dozen.
As for when you will start getting eggs I think it might depend on the breed. My white leghorns were the first to start laying, then the buff Orphingtons, then the brahma, and the polish didn't start laying till all the other breeds had been laying for several weeks.
I have 7 hens that I bought last April as chicks. I was getting 6-7 eggs a day but some are still molting and I have one brooding now on other hen's eggs, (I'm anxious to see what happens in 3 weeks with the brooding hen and the eggs), I'm still getting 5-6 eggs a day.
