Fred, I fought cushions in mine for a few seasons. If I saw it early, it always got worse, never better. In todays flock, if I see it, its sold off immediately as a layer in someone else's yard...I do still see it occasionally and I make note of what female/male pair is throwing itOH, and cushions. If you see those early? Chances a very good they get nothing but worse with maturity. Just my experience with my birds.
Anybody else?
