I defend exhibition poultry.
You said "before exhibition poultry, things were better." But have you ever seen what it was like before exhibition poultry?
There were no hybrid crosses, Rhode Island Reds, Barred Plymouth Rocks, Buckeyes, meat birds, buff Orpingtons, speckled Sussex, no dual purpose birds whatsoever.
Without breeding with the Cochins, (in true form, before they became aesthetic instead of dual purpose by those breeders.)
Without breeding with the Cochins, and then bred toward a standard they made up, the birds would get no where. That is unfortunately what happened to the Orpington. William Cook had beautiful egg and meat making machines, running smoothly, giant, well kept together. He sold them, but he didn't tell Europe how he wanted them to look.
They bred them fluffier and eventually they lost their dual purpose abilities as they made the standard how they wanted to.
Luckily, the original Orpington made it to America, and so we made the standard to his birds, and bred for great meat and egg qualities, keeping his version of the Orpington alive.
Without a standard, everyone decides to go off on their own directions, forgetting what the bird is actually supposed to look like, and the breed that was first there eventually goes extinct.
And, speaking of the Cochins. Without breeder and show interest, none of the new breeds would have showed up.
As you can see, it takes a group of people with a unified goal to have a breed. It can't qualify as a breed without more than one person breeding it. And without exhibition poultry, backyard poultry and industry as it is today would not exist. You have a much greater selection, with better egg laying and meat abilities.
So those are linked. And always will be.
