Measurements and Numbers for Chicken Coop Designs
If you are a backyard chicken farmer, you may be thinking of designing your own chicken coop after looking at all the different chicken coop designs on the Internet. This can be easy enough to do, but there are a few basic measurements to keep in mind when coming up with your own chicken coop designs.
What you should think about and consider is that every chicken needs at least 4 square feet each to be comfortable all the time. Doors on the chicken coop only need to be about a 1 foot high and 1 foot wide. Make sure they close tightly and latch, you can make them a little larger though. A raccoon is as smart as a toddler, so keep that in mind, since they love stealing eggs.
Roosts can be made from tree branches or old broom handles and step ladders, as long as they are about an inch and a half thick. Most chicken coop designs allow 18 inches between roosts, walls and other surfaces such as the roof or floor. Allow ten inches per chicken at a minimum and just make sure you can easily clean underneath them. Bantam chickens like a smaller diameter roost for comfort, so an inch is more appropriate.
When it comes to nesting boxes, most chicken coop designs allow for 1 foot wide, 1 foot deep and at least a 1 foot opening in the front. Putting at base on the front of 4 inches or taller will help keep the nesting material in. Also, a deeply sloped roof is the most desirable. You can estimate that you will need a nesting box for every 4 or 5 chickens, on the average.
Most chicken coop designs plan for an outdoor run so the chickens can be free to go in and out of the house. Chickens like to dig in the dirt, so loose soil 4 to 6 inches deep will allow them to roll in the dust, dig for grubs and enjoy the outdoors. The chicken coop needs to be roofed with a solid surface or fencing to keep predators such as hawks, eagles or owls from attacking you chicken. The fence shouls be 4 feet high.
When you are building protective fencing or the chicken run, most chicken coop designs recommend that you bury the fencing 6 inches deep and the outside of the perimeter should have the meshing bent upward in a 90 degree U-shape to discourage predators like dogs, rodents, raccoons and snakes that can come under the fence and steal eggs or chickens.
Chicken coop designs that allow for above ground chicken coops, such as mobile and stilted chicken coops that are in areas prone to flooding, recommend that above ground chicken coops have an inner floor that is 12 inches off the ground to prevent flooding and allow for ventilation, and keep the chickens off of the cold, moist ground. Also, the roofs should have a slope, at least 45 degrees, to ensure that the snow or rain won't accumulate inside your chicken coops. There are some chicken coop designs that are A-frames for this reason.
These are some of the basic guidelines that are common to many chicken coop designs but you can alter them slightly to fit your circumstances.
