Yes, cull for stubs on the legs and/or feet. And, it is recessive, so that means that both the sire and dam are carrying it. You might want to do some test breeding to see who is carrying it.
It is a common problem in the wheatens, but I've also seen it in whites.
Always a good idea to keep an "heir and a spare". :)
