I am looking for a certain kind of basket that is used for nests. These are spheres, like a ball, but with two openings opposite each other. I have no idea what type of caged bird they are made for, but they are big enough for my button quail. The nests are bigger than a softball. I have two in different sizes that someone bought at a market somewhere and gave me. I'd really like to buy quite a few more but don't know a source!
