Build 6, they might use 3. 5 or 6 is plenty, but I wonder why we do that as everyone seems to find they will only use one or two, maybe 3.
Or build a community nest. Just like nest boxes without the dividers. Or one divider separating space for 3 nests from 3 other nests. This is what I'm going to try this time. Actually I will have two standard nests because they're already built, then one community nest the width of 3 nests.
The two I already have are because I put 3 in my old coop and they won't use but one, so I took the others out.
