While commonly classed by fanciers with black and white as a " solid color,"! and handicapped with them in sweepstakes com- petitions, buff and red shades are the most uncertain of all in transmission and the most un- stable in the individual. With both red and black present in considerable amounts, there is a constant tendency for these pig- ments to separate and arrange themselves as in the black-red type. The black tends to go to the wing and tail feathers, the red to the feathers of the hackle and the back. Hardly more than one bird in a thousand in any variety will meet the Standard requirement for uniformity of surface color and hold that color until and through the first adult molt. For this reason an old buff or red bird that is sound in color is even more valuable as a breeder (compared with a similar young bird) than an old bird of other color types. The general rule in mating buff and red birds is to use birds of both sexes as near the Standard shade of color as possible and uniform in color.
