What is a "Split Tail" in poultry terminology?

In poultry terminology, a "Split Tail" refers to a tail with an obvious missing feather in the middle, which creates a visual effect where the tail appears split or not fully intact. This term is commonly used in assessing the physical characteristics of birds, particularly in competitions or shows. A split tail can indicate a defect or flaw in the plumage, which is important for poultry exhibitors to understand as it can affect the overall score or impression of the bird during evaluation.

The other options describe characteristics that do not align with the specific definition of a split tail. A completely plumed tail (fully covered with feathers) would not be considered a split tail. A tail that is split evenly in two does not accurately represent the condition of having a missing feather. A tail that curves upward is another distinct feature unrelated to the concept of a split tail. Thus, recognizing a split tail as one with a feather missing in the middle helps in understanding its significance in poultry judging and care.
