Sir I choose option A. There is no harm in adding a nest box... It doesn't matter to me if someone has had thousands of monitors or 2. Weather you have kept them 5 years or 50. Its how well they are cared for thats important to me. To just get bored with a species and let them have nesting failure....in other words let them die....aweful!

If I was done digging up eggs I would get the female spayed.
