Thanks AndyCap. In the meantime I got an answer from the PoultryClubSA. Apparently there are no Dorking breeders left in South Africa :(
They asked me to bring eggs from Germany.
Are there any Dorking breeders in South Africa?
I am a Dorking-breeder in Germany.
There are only few Dorking-breeder in Germany so there is a problem with inbreeding.
In August and September we will spend some time in South Africa. I wonder whether it is possible to get some Dorking breeding...
