And so I did. The nest boxes now have lids attached utilising four strap hinges per box. Due to the slope on the nest box, the strap hinges had to go on top of the bracing, as opposed to below. This caused some issues once the metal sheeting was placed above the nest boxes. But this was fixed by cutting about 25 mm off of the bottom of the sheeting. So now the nest box lids can be opened fully. The black flashing will prevent any water from getting inside.
I have to say that I preferred the look of the coop before the sheeting above the nest boxes was put in. But the sheeting will reduce the solar penetration. We'll see if I need to make any adjustments to improve the air flow. It would be cool to have openings which could lift up and hook onto the underside of the roof. However I will not go down that road for now.
I was slightly paranoid after the random planter made a comment about the nest boxes getting hot. So I put a thermometer inside the boxes. The good news is that the temperature does not seem to be any different from a shaded side of the coop. But the true test will be during the heat and humidity of summer.
Still a few more items to complete (such as some paint) before the move in date, but we are getting close. :)
We now have two hens which have gone broody, so it will be good for them to have a proper place to sit.
