Not a Welsummer to me, her tail is too upright and too much black into her tail feathers. Her comb is OK but she does not have the type of a Welsummer at all. Not all Brown Leghorns got flopped over combs. White earlobes, they should never have them for Welsummers.
Here is the standard for the Welsummers:
PLUMAGE COLOUR
FEMALE
Head golden brown. Hackle golden brown or copper, the lower feathers with black striping and golden shaft. Breast rich chestnut red going well down to lower parts. Back and wing bow reddish brown, each feather stippled or peppered with black specks (i.e. partridge marking), shaft of feather showing lighter and very distinct. Wing bar chestnut brown; primaries, inner web black, outer brown; secondaries, outer web brown, coarsely stippled with black; inner web black, slightly peppered with brown. Abdomen and thighs brown with grey shading. Tail black, outer feathers pencilled with brown.
IN BOTH SEXES AND COLOURS
Beak yellow or horn. Eyes red. Comb, face, ear lobes and wattles bright red. Legs and feet yellow. Undercolour dark slate grey.
SERIOUS DEFECTS: Comb other than single or with side sprigs. White in lobe, excessive white in plumage. Feather on legs, hocks or between toes. Other than four toes. Striping in neck hackle or saddle of male. Absolutely black or whole red breast in the male. Salmon breast in the female. Legs other than yellow. Badly crooked or duck toes. Any body deformity. Coarseness, beefiness and anything which interferes with the productiveness and general utility of the breed.
