I read a rather old publication recently that indicated the need for both light and dark brown leghorns in order to have correct and well marked male and female light brown leghorns. Has this been the experience of those here?
Your on the right track but I think you may be a little confused.
In 1874 when brown leghorns were admitted, there was no distinction between light and dark brown leghorns. They were admitted as just brown leghorns. As people began to breed them they had a general preference for the dark wine red males (dark brown) and the light olive gray females (light brown). Standards then changed to fit the trend. And the gap between male and female lines became larger and larger. This eventually lead to the need to double mate in order to produce both exhibition males and females.
That was the abbreviated version of the story. There was a huge controversy among poultry people as to whether or not that should've been done.
Eventually in 1922 the APA split the single comb brown leghorn into light and dark.
The rose comb brown got split into light and dark in 1933.
Today you do not need to cross the two varieties in order to consistently produce well marked males and females, of either light or dark brown.
I know lights have been crossed with darks to improve the type of the darks.
