Yes, the title is an incredibly silly pun based on Fort Knox for chickens, but here we go anyway.
A few years back we got chickens which is not something that anyone should do lightly. We picked up chicks at our local feed store when the first batch arrived in February. As we kept them warm and safe in the garage, we had our ultimate impetus to figure out the coop we wanted to build. We had birds, and these birds would need a home.
My then seven-year old was delighted with his dozen new pets and we played with them every morning and night. I would have already been inclined toward bird safety, but his attachment drove me to the utmost in coop security.
We planned where to put it by squeezing it into an otherwise unused corner of our yard. Some design considerations flowed from our unique location, but others are applicable to all builds. Most of these techniques were adapted from other folks solutions to known problems of predation.
Materials
Hardware cloth
We used hardware cloth everywhere and skipped chicken wire altogether. The openings in chicken wire are big enough for predators to reach a bird near the wall. Think of a grubby raccoon paw and what sized opening it would fit through.
I included windows in the coop, but they too are covered in hardware cloth. Where we attached hardware cloth near its edge, we secured it by sandwiching it with another board screwed on top. Staples have been reported to be pulled out by said raccoon types in order to access a coop.
Kreg slot screws
It’s completely non-standard, but we did all of our construction with the studs turned flat to parallel the wall. This afforded us extra inches inside the coop allowing us to maximize usable space. The Kreg made “toe-nailing” super easy and stable and doesn’t necessarily require their special screws.
Footers
After reading advice in online forums, we used a substantial 2 x 8 footer in the coop. This is also our only use of pressure treated wood. The footer does not directly contact the ground though. One edge rests on our retaining wall. The other three rest on a foundation of frustration. My darling husband dug a trench and set 9×9 paving stones on edge to create a wall to be buried. The idea being that any predator inclined to dig under the footer would find cement and be turned away.
Let there be light
We used SunTough roofing to keep the area as well lit as possible.
Technology
Water
The Little Giant Automatic Game Bird Fount Waterer is a genius design. It uses a Schrader bike valve and the weight of the water to trigger filling. It’s adjustable too. I change bike valves more often than I might like, but I haven’t had to replace the whole thing.
The Upside to Big Brother
When we first brought the chicks home, I worked a few miles away in an office. I wasn’t comfortable leaving such helpless little creatures completely unmonitored. I bought a weather station with remote reporting and a wi-fi camera. Both were inordinate amounts of trouble to set up to access through my home firewall, but once it was done I could watch the chicks from my desk and see that the heat lamp reached an area that was adequately heated for their age. This setup was priceless for my piece of mind while 12 helpless bodies roamed in a pile of sawdust with a fire hazard suspended above.
Later when the girls moved to the coop I was able to move the camera along with them. I mounted one inside the coop and I could see which bird laid which egg and at what time. I got another camera on sale and mounted it outside which allowed me to record the nighttime comings and goings of our backyard. I learned that we have mice, rats, raccoons, opossums, foxes, and skunks. I also noticed that no one creature spent any time near the coop. My plan was to be able to see where a vulnerability was before it became a full-on blood bath.
Ador door
This works. The interface is maddening, but it has been mostly reliable for three years. We had the drive give out, but bought their replacement. I had a regular lantern battery last for over a year and then I added a rechargeable with a small solar panel. This setup didn’t last any longer. My husband recently hardwired it.
