Henderson’s handy dandy chicken chart has a comparison of over sixty chicken breeds. Compares type, origin, egg color & productivity; egg size, comb and skin color, earlobes, brooding hardiness, maturing and behavior. If you are thinking of raising chickens for eggs or for meat this chart could really come in handy. Sage Hen Farm Lodi shares the chart and it is fantastic.
