That will work great for them to hide in from the sun. Nice job
I will put more shade cloth up as well, over the old henhouse. The new one is up against the fence and we have Colorbond fences, and as they are metal they get hot. The old one is by the wire on the other side, so if I can properly shade that, it should be cooler. Charlie laid her egg today in the garden nest and the three of them have dug into the garden by the house for the afternoon.
