Not sure if this has already been posted but the Portland coop tour is Saturday, July 25th. I know this was asked about a couple of months ago in another posting. I just bought my guide today and it looks like it's going to be a lot of fun. There's a bunch of coops on the tour and should make for a full day of visiting and looking at coops/chickens. Here's a link:
