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.
The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers.NASAâs Voyager 1, humankindâs most distant spacecraft, is around 125 AU.he scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance.
