Is it too close to the roost?

Some curtains hung in front of the boxes will make them more inviting as they add dimness and privacy.
This is how mine are set up. The 2x4 in the upper left corner is my roost.
These nest boxes are obviously well liked! The box these two are in is 12x12. I was surprised when I opened up the back to check for eggs and saw 2 fluffy butts in there.
