New coop.

[Athiena14]

So it's funny to try and get 4 unwilling chickens /roosters to go into a new coop. The area is in my old barn that had been set up for chickens, complete with nesting boxes. All I had to put up was a door. I was gonna ask how high was maximum height for boxes, but they jumped up to the floor of the second floor... yay now gotta put plywood down on it XD. There isn't much natural light going into that part, should I put in electric lights? They only go in during night and if the weather is bad

You could put LED lights up (no extra heat) if you feel like it’s too dark.

You could use mesh instead of plywood.
Roosts should be higher than nests.
Here's some height tips:
