How do knock knees work? I have never had to deal with them, but have some birds of a beautiful strain, but they are knock-kneed. Will ANY normal kneed birds result from a knock-knee to knock-knee mating, and what about a knock-knee to a normal kneed bird (I could breed them to my other strains)? I would hate to cull them, but probably will if I won't be able to get rid of the knock knees. Thanks.
