This is actually your 'coop'... as it's the only enclosed area.Raised floor/roosting area: 2.5 X 4 ft (10 sq. ft)
They'll end up sleeping in that nest.
I'd move the nest down below, and add a cover to it, and put an actual roost in this area. Once those birds grow up it may get crowded in there.
Curious.....
Where in this world are you located?
Climate, and time of year, is almost always a factor.
Please add your general geographical location to your profile.
