We finally got a break in the weather and started construction this past weekend - we'll get it finished this weekend and just in time! The chicks are over 6 weeks old and really need to move out on their own. First pic is of the site - used to be my veggie patch but was unused the last year or two: It's below the top of the wall so our neighbor won't see it (he knows it's going in but I don't want him to get fed up with his crazy neighbor ) Here's the construction so far: We buried galvanized sheet metal (a flattened rain gutter) around the perimeter to prevent digging (it only goes about 6-8 inches underground but I hope that will be enough). 1/2 inch hardware cloth all round the run (and overhead). Fence boards for siding and flooring (the boards at the near end will be trimmed off just below the top of the wall). John has insisted on stainless steel screws, and of course everything must be level and square, so it's much nicer than anything I could have built on my own. Really hope it's raccoon-proof!
