just depends what you are breeding for. I have a single comb, utility grade silky hen. She also has an unpleasant personality, but she is an EGG LAYING MACHINE, just about like a leghorn. I am raising a batch of her babies right now, and I am not getting rid of anything until it crows, because in this case I don't care if the comb is reddish, or single, or it is missing a toe. The father is much more typey, bearded and docile than the hen, and some of the babies are surprisingly typey, but I am not culling out the ones that are less typey, because my primary criteria for this cross is better looking, great laying, occasionally broody, good mothering silkies, preferably without profuse feathering, huge topknots, super docile dispositions... On the other hand, if i was shooting for exhibition birds, there are only two in the bunch with "promise" at this stage, three weeks. The rest would have been gone two weeks ago.
