Chicken Tail Angles

One may wonder why it is important to know anything about angles and the degree of the angles in a chicken's tail. As poultry is judged and identified, there are standards for the angle of the back, wing or tail, with respect to the horizontal or back of the chicken.

The angle of the tail helps one to identify the breed of chicken. The range of tail angles for males is from slightly below horizontal to 75 degrees and from slightly below horizontal to 70 degrees for females.
