The Fullback is a breed of fancy pigeons developed over many years of selective breeding. Fullbacks and other varieties of domesticated pigeons are all descendants of the rock pigeon (Columba livia). The breed is known for the frill or curls on the wing shield feathers. The feather curl should also be present at the ends of the foot feathers or muffs.
At least three exhibitors must enter ARC and ARCP Frillbacks in 3 of 5 American Frillback shows for three years, with judging score progress before it is deemed appropriate. Fullbacks produce many colors that the AFC needs to recognize because they are not standard and do not reproduce consistently. Fullbacks can carry numerous colors in many different patterns, such as pied. These colors are not recognized as standard but are very common. Fullbacks are slightly larger than other colored pigeon breeds, with long tails and wing feathers. Head Shell-crest and plain-head are found in all colors of Frillbacks. A plain-headed Frillback should have a slightly oval head with no flat areas and a forehead with a distinct stop at the wattle. A shell-crested Frillback should have a thick shell crest on the back of the head with rosettes on each side. The range should stand off the chair.
Eyes The eyes should be in line with the beak. A reddish-orange is desired in all colors except the shield marked. Shield marked desire a black or bull-eye”. While pearl, gravel, and cracked eyes occur, they are undesirable and considered significant faults. Beak, The beak of a Frillback is long, with the upper beak often being slightly longer than the lower beak. The visor is dark on red and blue grizzles, black on blacks, light on yellow, horn on silver, and flesh-colored on all other standard colors. The wattle is thin and white in all colors.
Muff, The muff of a Frillback, will vary; however, 2 to 3 inches is a desirable length. Frill, The curl of a Frillback covers its entire wing shield. No areas should be uncovered. The last row of circles spans the whole length of the wing. Frills form a distinct ringlet curl at the end. The bottom of the muff is also frilled. Tail and flight feathers have a particular wrinkle.
