Another thing Broomhead wrote which really caught my attention. In discussing the Light Sussex, he states that much has been made of the long keelbone in the breed. This is a marker for quality in a meat producing bird. He also states that too long a keel isn't found in the better egg layers. So Broomhead says in a dual purpose breed like the Light Sussex, not to worry too much about the length of the keel, instead to put more effort into the length of the back. I have never seen this mentioned anywhere else.
How does concentrating on the length of the back conpensate for an average , rather than a long keelbone? In other words, instead of concentrating on an extra-long keelbone, Broomhead seems to write that concentratng on length of back will accomplish the same thing...and by extension seems say that doing this will give one a bird which is truly dual purpose, both a quality egg layer and meat bird. I don't get where the length of back comes in as a favored virtue?
Thanks for any enligtenment.
