That's true, but we don't need to act like putting a bird on a scale is a novel, foolish, and frivolous thing. All sorts of folks in the ag industry weigh things, corn, cows, etc. It is done all the time. No need to dispute it.
Chris and Fred, you are absolutely right. There is only one description of the breed, and it applies to all of the uses that the bird can be used for. When people are told to " read the SOP", it means read the whole thing. The individual breed description is not enough.
