Lots and lots of pictures submitted from people around the world of every breed you've heard of and more.

This is Henderson's Breed Chart. It has only one picture of each breed
and then gives information on rarity, class and type, egg size colour
and productivity, how much the hens weigh, comb type and skin colour,
broodiness, hardiness, how fast they mature and their behaiviour.

Another site like Henderson's Breed Chart. Slightly more wordy.

Click on 'choose your breed' for a page which will take into account
several different options (large or bantam, flighty or not, number of
eggs, calm character).
