"I was the happy owner of 2 cockatiels this summer, but that number has mulitplied and now I own 11 cockatiels!!! My girl bird, Gayle laid eggs twice this summer. I noticed the "mating ritual" going on in the spring, and so I decided a nestig box would be best. I was concerned that the box might not feel "homey" enough for my birdies, but apparently they thought otherwise. I eneded up buying another box, and it has been the home to the many babies born this summer. What would I have done without the box? No idea, I don't even want to know, I am just glad I have one....I mean...two."
