There are shallow rollers, and there are deep rollers. You can’t breed two deep rollers or their young, their offspring, will roll all the way down, hit and die. Agent Starling is a deep roller, Barney. Let us hope one of her parents was not.
When we breed Rollers we do not try to produce the roll, we endeavor to control it.
It is certain that colours and markings cannot be cultivated without a decided loss in quality of deep spinning.
Without the speed, quality and depth are insignificant.
Put em’ up, or shut up.
Depth of roll is the most over emphasized factor in performance.
Velocity spinning is the single most important factor in the roll! A bird may have everything else, but without velocity of spin in its repertoire, it has nothing.
Well done is better than well said.
Garbage in, garbage out.
It is not only fine feathers that make fine birds.
Envy can be a positive motivator. Let it inspire you to work harder for what you want.
