Rhodebars are a cross between American Rhode Island Reds and Brussbars, an autosexing English dual-purpose breed. The result is a bird that's an excellent layer, autosexing (yay, autosexing!!!) but slimmer than the Brusbar and probably not as good a dual-purpose bird. Brussbars are GORGEOUS! (So are Rhodebars IMO -- and they are hands-down my sweetest-tempered birds). Rhodebars are predominantly red with wonderful black-and-white barring in the roos, and lay light brown eggs. . Isbars are from Sweden, not autosexing (bummer!), good egg layers (about 250 a year) of green eggs -- mine lay a nice minty green, some lay mossy ones, one friend says hers lay puke-green eggs, lol! They come in blue, black and splash, are fairly light-weight, and easygoing. (At least mine are.) They're also supposedly good layers through the winter, which would be nice! They're both newer breeds, developed in the middle of last century. Here's the feathersite page for Isbars with lots of pretty pictures: http://www.feathersite.com/Poultry/CGD/Isbar/BRKIsbar.html Here's the Greenfire page for Rhodebars: http://greenfirefarms.com/store/category/chickens/rhodebar/ And here's a page with the whole British standard for Brussbars and a very pretty roo pictured at the bottom: http://autosexing-poultry.co.uk/wordpress/brussbar/ In my ongoing quest to own one of every breed of chicken known to man, if anyone goes to England and wants to smuggle me one home under her coat? I'd be VERY grateful, lol!
