Comments:
The fallow colour variety inherits recessive. This means that hen and cock both can be split. It cost much more time and care to develop recessive colour varieties than sex-linked colour varieties.
The best combinations are:
cock 1 x hen 2 or cock 2 x hen 1. The results are the same, fallow an split fallow cocks and hens.
Useful for bringing in fresh blood are the combinations cock 3 x hen 1 or cock 1 x hen 3.
To be avoided are cock 1 x hen 1, can give eyesight problems, cock 2 x hen 2 or 3 and cock 3 x hen 2. It is not possible to discriminate split fallow.

Abbreviations:
(f) = fallow
( /f) = split fallow
(-) = wildtype, no mutation factor

Colour:

dark yellow: best choice
bright yellow: good choice
