Sadly not all strains of the same breed will lay the text-book number of eggs since there has been a large amount of selection for specific traits desirable in the showing circuit and sometimes egg production has actually been bred out of these strains.
An astronomical unit (AU) is a measure of distance often used in astronomy, equal to the distance between the Earth and the Sun. In terms of more common units of measurement, an AU is equal to about 93 million miles (150 million km), or the distance light travels in a little over eight minutes. The symbol AU is most often used to represent the astronomical unit, though less commonly you may see UA used instead.
Radians measures the angle in terms of the length of the arc that will be subtended on the circumference of a circle of one (dimensionless) unit. It can be found by the equation: 2*pi*(degrees/360) Grads, however, divides the right angle into 100 parts instead of 90. It is often used in artillary measurements as it is often simpler to world of a base-10 than a base-9. Gradians To Degrees. radians are used to evaluate things in polar.
