They are hard task masters!
I dunno about wiring all that in; but, I have to say I do like the idea of the LED micro switch setup to allow you to have light to see when you collect eggs. We have talked about wiring up electricity out there to help extend the days in the winter. I doubt it will happen. With the translucent roofs, and the number of birds, the reduction in laying isn't going to be as big an impact as all that...be a nice break, actually
Our birds will be up and in bed by the time the big light in the sky goes out. They are already going to bed just as the last bit of the sun sinks on the horizon. Dusk is what I grew up knowing it as...where the sun's no longer in the sky, but there is still a touch of light left by which to see. So, I'm not sure we'd need lights on the ramps....but, motion activated lights would be beneficial for the outward facing walls of the runs. My step son has been making noises about running water and electric out there for me (he's a landscaper and arborist) because, "You never know when it will be handy. Besides, having their water here will save you time in the morning." He wants to hook up a fully on demand system for them for watering.
Of course, he's also the one who overheard a random comment I made to his dad about the path being worn through my grass and how I wish I could do something about it....I came home the following day and he'd laid a rock path. I got an email this morning from his father telling me he's building a little rock 'bridge' to go over the natural wash that I have so that the two different types of stone walk ways (he's joining it to the path by the house) will "flow better".......I've got two over achievers in my home, right now.
If the three of them (my husband, my ss and your DH) ever got together on a project....watch out world.
