Personally I like the idea of periodically testing and culling birds that test positive or are showing signs of disease. Seems like that would be the best route for breeding birds resistant to disease. Because if wild birds have it, there is always a chance of outdoor chickens contracting the disease. Not a guarantee, but that chance is still there and always will be. If chickens can catch the disease from wildlife, which it seems like they can, the only solutions are vaccinating every single chick or breeding for birds resistant to the disease. I've always been against overvaccinating, so for me breeding for better birds seems like the solution.
Not that I breed currently, but I'd be happy to support someone who did and buy birds from them.
