I have been building this for several weeks. It is 23" tall. Today somebody told me that it is too tall for quail. I had planned to build it very sturdy so that it would last a long time and I could use it for finches or diamond doves at a later date if I wanted to. Do I need to cut it down for quail and forget about finches/doves? If so, to what height? How real is the possibility of a bird breaking its neck by hitting the ceiling?
