Did you know there are more than 200 breeds of chickens? Why do you care? Besides color, plumage pattern, style of comb and wattles -- somewhat cosmetic considerations -- chicken breeds differ on everything from personality, to broodiness (tendency to sit on eggs to hatch them), to winter hardiness and even egg color! Plus, some farmers raise them to show, or breed rare varieties to keep them going, or just because they like that particular breed.
