Thanks for all the responses! In terms of the nails and screws, It's what I found on home depot's website. I was trying to find smaller packs. Their site is pretty clunky and I can't really visit the stores at the moment. I'll see if I can find better. In terms of siding, that is my other big expense. I put a couple options as at 5'x5', getting all the plyboard or whatever ends up being just as expensive. I was doing 5'x5' as we were planning on getting regular sized chickens (maybe 6?). My wife wanted austrolop and amaraucana. I kind of wanted Jersey giants but maybe they are too large. I wasn't planning on a run yet, and we live in the Seattle area, so it rains a lot and will eventually need it.
