Sex Linked or Auto Sexing ?
There appears to be much confusion over the difference between auto sexing and sex linked birds. Although both are sexed by the colour of their down, for a sex linked combination you need to keep both the parent breeds for example; if you wanted a gold/silver cross of Rhode Island Red (being gold) and Light Sussex (being silver) then you will need to keep both of those breeds to produce a chick that can be sexed on hatch because the sex linkage will not work for a second generation, only on the first generation crosses. If you put the adult chicks back to the father you will not be able to tell the difference between the boys and girls on hatch as you will simply have a hybrid
With an auto sexing breed because it is a pure breed ie. it breeds true, then whichever way you do the cross, father to daughter, mother to brother, aunts, uncles, whichever way you cross you will always be able to distinguish the boys from the girls on hatch because they are a pure breed.
There is a bonus to keeping more than one auto sexing bred and that is crosses of auto sexing birds. Virtually any cross of an auto sexing breed, in either way, will give you birds that can be distinguished on hatch by the colours of their downs and give a very good hybrid with excellent laying ability. There is only one cross that isn’t recommended and that is the Buff to Silver cross
