Depending what you want chickens for, mostly for pets or mostly for eggs, for pets, Silkies and Cochins are probably the two most popular breeds, they are not very good egg layers but are very friendly. So far as more layer breeds go, for egg numbers alone, the Red Sex Links (Golden Comet, Red Stars, ISA Browns etc) for brown eggs and the commercial White Leghorns for white eggs are probably the most popular layers around. If you want breeds that don't lay quite as well but will lay for a longer time, Orpingtons (lots of people really like these, great pets though broody), Australorps, Plymouth Rocks, Sussex, Delaware and Wyandottes are some other popular breeds that are usually pretty easy to get along with, they all lay different shades of brown eggs. If you like colorful eggs, the Easter Egger, often sold as Ameraucana by hatcheries, are a fun breed because they usually lay green/blue eggs, and they tend to be very nice birds, and then there are the Welsummer and Marans for those dark brown eggs... have fun deciding!
