hi everyone..im new in this industry,i've setup a birdhouse in a shop lot since 6 months ago, however there's not even a bird nest yet. i've throw out all my saving for this investment, is there anyone that can help me?

and here are a few things that im curious,
1. should i destroy all the partition? my sifu say it won't effect birds from coming in.
2. what is the best humidity and temperature in birdhouse? my sifu says its not important.
