CHEAP BUT PRACTICAL NEST BOXES. 

 These are empty egg crates piled one atop another from floor to roof of squab 

 house. Each egg crate is two feet long, one foot wide and one foot deep. The 

 partition in the middle makes two nest boxes, each one foot square. Into each of 

 these nest boxes a wood nest bowl is placed. The birds build their nests in these 

 wood nest bowls.
