Now that I got that off my chest.........
Believe it or not, in breeding to the Standard, to some degree we are actually breeding for the culls! Our desire is to inbreed in such a way that the hidden recessive traits rise to the top and can be discarded. We are not at all dismayed by those faults that occur in our lines. We want to know what's their so that it can be taken out.
Sometimes we do have to bring in an outside bird to help set something in our line. The goal is to develop a line/strain/family where that is no longer necessary to do. With a large enough hatch you can continue to inbreed for many many generations with no detrimental effect.
