Culling doesn't always mean killing, Angel. It means removing.
Sometimes a chicken is not show quality, so instead of a breeder using that particular bird in their breeding program or showing them, they will find someone who is not interested in breeding, but just having a pretty chicken in their yard to crow or lay eggs or be a pet.
I have a couple of ducks from Holderreads lines, but they are pet quality, which will happen out of show stock. They are pretty and good pets, but not for show.
