The principal colours now bred are Buff, Cinnamon, Partridge, Grouse, Black, and White. The Buff and White are the most popular. Buff birds may have black in the tails of both sexes, but the less there is the better. Black-pencilling in the hackle is considered objectionable at good shows. The cock's neck hackles, wing coverts, back, and saddle hackles, are usually of a rich gold colour, but his breast and the lower parts of his body should match with those of his hens. Buff birds generally produce chickens lighter than themselves. Most birds become rather lighter at each moult. In making up an exhibition pen, observe that Grouse and Partridge hens should have a black-breasted cock; and that Buff and Cinnamon birds should not be placed together, but all the birds in the pen should be either Buff or Cinnamon. The Cinnamon are of two shades, the Light Cinnamon and the Silver, which is a pale washy tint, that looks very delicate and pretty when perfectly clean. Silver Cinnamon hens should not be penned with a pale Yellow cock, but with one as near to their own tint as can be found. Mr. Andrews's celebrated strain of Cochins sometimes produced both cocks and hens which were Silver Cinnamon, with streaks of gold in the hackle. In Partridge birds the cock's neck and saddle hackles should be of a bright red, striped with black, his back and wings of dark red, the latter crossed with a well-defined bar of metallic greenish black, and the breast and under parts of his body should be black, and not mottled. The hen's neck hackles should be of bright gold, striped with black, and all the other portions of her body of a light brown, pencilled with very dark brown. The Grouse are very dark Partridge, have a very rich appearance, and are particularly beautiful when laced. They are far from common, and well worth cultivating. The Partridge are more mossed in their markings, and not so rich in colour as the Grouse. Cuckoo Cochins are marked like the Cuckoo Dorkings, and difficult to breed free of yellow.
