Most breeders don’t know the importance of Selection. The truth is, selection is the difference between success and failure. You cannot create or improve a strain without some knowledge of selection.
However, when you talk with breeders, even experienced breeders, it’s amazing to see how little they know about the proper structure of the bird, the conformation and type of the birds, and the defects that exist. They select and breed for the wrong things, and then they wonder why their fowl are not progressing as they hoped. Their only resource is to add or infuse outside blood.
