Good luck with the bird house! My parents have a few on their back deck and it took a few years but eventually at least one of them took up a resident. It’s fun to watch them when we are over there. Unfortunately on the other side of town, I have a lot of black bear activity any type of bird feeding is Ill-advised.
On the topic of blue jays, my dad has built up a relationship with a population over the past 10 years or so. He absolutely loathes crows and after finding out blue jays fight off crows, he began his offerings of peanuts. At this point, they come to the deck proactively for their peanuts and in return he hasn’t seen a crow in the area for years. The payoff has worked. Iv seen them chase off crows and even go at a hawk who took interest in the yard. They leave all the little birds alone though.
