Nope, they're totally different. The Blue Andalusian is a very old breed of chicken that originated in Spain. They're good layers of creamy white eggs and are the original "blue" chicken. They're also an APA recognized breed and endangered. The Isbars are a fairly recent creation (1950's - 1960's) that originated in Sweden. They lay green eggs. The original breeder was attempting to make an autosexing green layer, but never finished breeding in the aitosexong qualities. I think the breeds used to start the Isbar were Crested Cream Legbars, Rhode Island Reds, and New Hampshire's. They are not a recognized breed.
