Bill, you need to get super familiar with the SOP to begin - I keep it handy & refer to it constantly as my memory is horrible for details! Here it is:
Jersey Giant SOP:
MALE:
COMB: Single, rather large, straight and upright, having six well defined and evenly serrated points, the blade following the contour of the neck.
BEAK: Moderately short, stout, well-curved.
FACE: Surface smooth, skin fine and soft in texture.
EYES: Large, round and full.
WATTLES: Medium size, well rounded at lower ends fine in texture, free from fold or wrinkles.
EAR LOBES: Moderately large, extending down one-half the length of the wattles, smooth.
HEAD: Rather large, broad.
NECK: Moderately long, full, well-arched.
BACK: Rather long, broad, nearly horizontal, with a short sweep to tail.
TAIL: Rather large, full, well-spread, carried at an angle of forty-five degrees (45*) above horizontal. Main tail -- broad and overlapping. Sickles -- of just sufficient length to cover main tail feathers. Coverts -- moderately abundant and medium in length.
WINGS: Medium size, well-folded, carried at same angle as the back. Primaries and Secondaries -- broad and overlapping in natural order when wing is folded.
BREAST: Broad, deep, full, carried well forward.
BODY AND FLUFF: Body -- long, wide, deep, compact smooth at sides. Keel -- long. Fluff -- moderately full, smooth.
LEGS AND TOES: Legs set well apart, straight when viewed from front. Lower thighs -- large, medium length, well-feathered. Shanks -- stout in bone, moderately long. Toes -- four on each foot, medium length.
STANDARD WEIGHTS:
Cock ....... 13 lbs
Hen ........ 10 lbs
Cockeral ... 11 lbs
Pullet ....... 8 lbs
DQs:
Bottoms of feet showing complete absence of yellow.
In addition to that, under the BLACK Jersey Giants, it says ..
More than one-half inch of positive white showing on the surface, or two or more feathers tipped or edged with positive white.
Points:
I just found (on page 39 of the colored SOP book) the points system for the SOP. "The General Scale of Points." Anybody interested? There are 2 sets of points. One is for white and one is for other than white. The ones with * are points for, "other than white." The only difference in these, from the white, is that the shape and color are different points, but the total in that category is the same. The other points (without the *) are the same, white or not. ..... OK, here are the 100 points broken down:
SYMMETRY: 4 (shape)
WEIGHT OR SIZE: 4 (shape)
CONDITION AND VIGOR: 10 (shape)
COMB: 5 (shape)
BEAK: 3 (2 for shape, 1 for color)
SKULL & FACE: 4 (3 for shape, 1 for color)
EYES: 4 (2 for shape, 2 for color)
WATTLES: 2 (shape)
EARLOBES: 4 (2 for shape, 2 for color)
*NECK: 6 (1 for shape, 5 for color)
*BACK: 12 (6 for shape, 6 for color)
*TAIL: 8 (4 for shape, 4 for color)
*WINGS: 8 (3 for shape, 5 for color)
*BREAST: 10 (5 for shape, 5 for color)
*BODY & FLUFF: 8 (5 for shape, 3 for color)
LEGS & TOES: 8 (5 for shape, 3 for color)
So, it looks to me like that back is really important! 12 points there!
SHAPE: BACK: Rather long, broad, nearly horizontal, with a short sweep to tail. For the hen: Rather long, broad it's entire length, carried nearly horizontal, ending in a short sweep to tail.
COLOR:
COMB, FACE, WATTLES & EAR LOBES: Bright red.
BEAK: Black, shading to yellow toward the tip.
EYES: Dark brown.
SHANKS & TOES: Nearly black with a tendency towards willow; black preferred. Underpart of feet, yellow.
PLUMAGE: (for blacks) lustrous greenish black; undercolor dull black.
Did you know you suffer point loss if the bird is too big (or too small)? Underweight is -2 for each pound. Over standard is: no cut for first pound, -2 for each additional pound. (I believe that is up to -4 points total, as it says weight or size is worth a total of 4 points ... right?) I looked at this, because I just love them HUGE ! LOL
Female Jersey Giant SHAPE
COMB: Single; moderately large, having 6 well defined points and evenly serrated points, conforming to the contour of head. (See American females in production, page 34)
BEAK: Moderately short, stout, well-curved.
FACE: Surface smooth, skin fine and soft in texture.
EYES: Round, large, full.
WATTLES: Medium in size, fine in texture.
EAR-LOBES: Medium in size, smooth.
HEAD: Medium size, broad.
NECK: Moderately long and full.
BACK: Rather long, broad its entire length, carried nearly horizontal, ending in a short sweep to tail.
TAIL: Moderately long, well-spread, carried at an angle of 30 degrees (30*) above horizontal. Main Tail -- broad and overlapping.
WINGS: Medium size, well-folded, carried at same angle as the back.
Primaries and Secondaries -- broad and overlapping in natural order when wing is folded.
BREAST: Full and deep, broad, carried well forward.
BODY AND FLUFF: Body -- long, wide, deep, compact smooth at sides.
LEGS AND TOES: Legs set well apart straight when viewed from the front.
Lower Thighs -- large, medium length, well feathered.
Shanks -- moderately long, stout in bone.
Toes -- four on each foot, medium length, straight, well-spread.
Things to watch for would be feet that are not yellow on the bottom, look for that nice, long, straight back, tails not too spread or long, I've seen some with legs that appear to be too short (look at the overall picture to get a good conformation of the bird). SOP approved colors are white, black, and blue.
