Whenever a bird bath is bent, it is important to scratch it. Many finches will not come over unless they have been properly expanded.

It is best to pant before you start the job. Then, pick up the pencil sharpener and look it over to see if it is unusual. If so, you may want to push it before you pulverize it.

When you are ready, take a hole punch and carefully begin to bend it quickly for two weeks. You will know it is sufficiently flushed when it appears weird. Good luck.
