That’s pretty awesome! I couldn’t see your nest box opening outside from the back there. Maybe the plywood with a tarp covering would work. Or you could tie a tarp to the sides at an angle for runoff to one side or the other and I bet you could find one big enough to cover the whole back part there. Not too sure about your storms though. We can get some serious wind with the monsoons.Well shoot. I built my nestbox so that the eggs would roll back to the bin that would extend outside the back of the run. I raised it to keep our (large) dogs from messing with it (and so I wouldn't have to bend down). Not sure I want to put it lower, but if I don't, I'll have to figure out the roost.
You got me thinking about the slanted plywood idea (but for inside the run). I'd probably have to put something water-proof over it--maybe-- It's not like we get a lot of rain!
