Single comb or wrong number of toes are not nearly as bad as keeping a breeder that produces wry tails or crossed beaks. At this point I have sufficient birds without comb or toe faults that I will only keep it for breeding if I consider it really special in other areas.
For example, with my duns, of the two young adults I have, the boy has a single comb. Other than that he has all silkie features, and is far better in quality than the previous generation, some of whom had walnut combs--that were very oversized, gnarley and twisted. However, dun is a project, and anyone getting dun birds needs to be prepared to spend time improving the birds and removing faults.
Another example, I've mentioned my partridge pair with incorrect toes (one has 4 per foot, the other 6 per foot). Both have excellent type and colouring, so I currently have them as a breeding pair--depending on the chicks produced as to what I will do with them.
I definitely believe in full disclosure--I'll happily go through both the good and bad points of each individual bird.
