Welcome to BYC! There are an awful lot of blue laying breeds or strains out there nowadays. I agree with EggSighted's assessment of Ameraucanas. They are good layers, but they taper off after their first year. The hatcheries often have blue egg laying strains, like Whiting True blues, which might be worth a look. Cream legbars are popular because they are new, so they might be worth a look, too. Lots of choices. I hope you find some good birds!
