Hens typically lack which of the following features found in cocks?

The distinguishing characteristic of hens compared to cocks is the absence of saddle feathers. In poultry, saddle feathers are the elongated, pointed feathers found on the back of male birds, particularly near the tail. These feathers are prominent in cocks (male chickens) and contribute to their more elaborate plumage and overall appearance, which are important for attracting mates during breeding season.

Hens, on the other hand, have a different feather structure that is less ornate, promoting a more camouflaged and subdued appearance, which is beneficial for nesting and protection of their chicks. This difference in feather types is a key aspect of sexual dimorphism in chickens and helps in identifying the gender of the birds during poultry shows and related activities.

The other features mentioned, while they may differ between hens and cocks, do not present as clear a distinction related to mating and attraction as the saddle feathers do. For example, while cocks may display bright colors and longer tails, these traits encompass a broader range of characteristics rather than the specific features that set them apart in sexual differentiation, which is primarily illustrated through the presence of saddle feathers.
