Okay, here's the plan:
Mike has reinforced the chicken yard with welded wire field fencing and repaired the damaged side with roofing tin. He moved the nest box away from the fence - we now have to go inside the yard to collect the eggs, which is kind of a drag but oh well. We are using a baby monitor to listen in on the chickens. I doubt any dogs could get in there now, but if they try, we'll hear 'em right away. It's very reassuring when we awaken during the night, to only hear coquis, rain, and soft little chicken sounds (and we have been waking a lot these past nights, believe me.)
We're going to put up fencing around the back half of both lots, one big fence to encircle and protect the backyard farm. This will also serve to keep out the wild pigs that will no doubt be attracted to our sweet potato beds and fruit trees just before harvest time.
The piggery is still a go. Right now we're waiting on the architect to stamp the plans, then the County gets to have another go at them. Once the permit is finally issued, it should only take a couple days to build. Of course, it will have to be inspected before we can really use it.
Though we're still reeling from the loss to our flock, life goes on and so do we. The injured birds seem to have recovered, and the chickies are pretty much settled down. Egg production, however, has dropped considerably with the loss of three of our best layers, and the shock to them all.
You knew we couldn't really be stopped by mere dogs, didn't you? We just have to adapt to the current circumstances and move forward. Onwards!
