poultry wire of the type shown in the vid has mesh too big to keep out small voles and adolescent gophers — if you can get it, use galvanized hardware cloth instead, it has a smaller mesh. this is usually only a big problem if you have shitloads of gophers around though.

you can also use doug fir which will be a lot cheaper, but it will rot eventually. but if you are on a budget and don’t need the beds to last 10 years, it works.

the nailgun will get the job done quick and easy but for a nice finished look you can drill in 3/8″ pilot holes on the corner joins, and fit galvanized lag bolts into them.
