1. 9

2. 10

3. 11

4. 12

The correct answer is: 11

The correct number of primary feathers present on a wing of a white leghorn hen is 11. Primary feathers are crucial for the bird's flight, and in poultry species such as the white leghorn, this count is standardized. Each primary feather plays a significant role in providing lift and maneuverability during flight, contributing to the overall wing structure and function. The 11 primary feathers are evenly arranged and coded for efficient wing performance, which is essential not just for flying, but also for maintaining stability and control during movement. This specific count is based on the physiological and genetic traits of the breed, making it an important piece of information for poultry judging and breeding practices.
