Nest Box Question

[braden]

What diameter are the nest bowls?

I have been reading that each breeding pair needs 2 nests, is that 2 nest bowls or 2 boxes?

Is it better to make one long nest box to house 2 bowls or smaller boxes for 1 bowl each?

Is it better to have some room in the nest box, like walking room outside the bowl like box would be 14 deep x 24 long, or more of a 14 x 14" square box?

Want to make sure I get this all right the first time around Thanks!
