Oh yeah, we're "organic" so no pressure treated lumber was used in the construction. I clad all lumber that comes into contact with grass or soil with lapped seam aluminum flashing. All aluminum and steel products are isolated in a way to prevent galvanic corrosion, etc.

The birds like it. They put themselves to bed every night at dusk, and the girls seem to love laying in the nest boxes. We have a couple of fake eggs in two of the six boxes, but all get used.

Our dominant rooster stands guard over the ladies while they lay in the morning. Its really sort of sweet to see.
