John,
We put up three houses the last few years and the number of martins showing up has been on the increase every year. Last year we lost one of the houses to a storm, but I will get it back up this year as right now I count over 60 birds living in our 36 rooms! I am hopeful that next year, we should have nearly 100 birds in the 60 rooms we will be providing!!

I think I will stop at 4 houses regardless of the number of birds that show up. At 90 rooms, that should be a lot of chirping!!
