So exactly how tall should a chicken coop be? A chicken coop must be at least ~3.5 feet tall on the lowest side of the chicken coop. This height allows for 20-inch high rest bars, 4 inches of bedding, 1.5 feet between the top of the rest bars and the bottom of the vent, and 5 inches of ventilation on the shorter side of the chicken coop. If you raise your chicken coop high enough, your chickens can explore underneath and possibly find some tasty bugs that take advantage of shade and humidity. I argue that a chicken fence around 6 feet tall is the perfect height in most situations, even if you live in the middle of nowhere.
These laws are in place to help ensure that strict biosecurity measures are in place and that the risk of disease in chickens is kept to a minimum. Anxious raccoons and wild cats can do little work from this fence and access your chickens. And if you're simply interested in purchasing a high-quality pre-built chicken coop, I highly recommend Rita Marie's Chicken Coops. Another great advantage of having a chicken coop raised off the ground is that you don't have to worry about the driveway being covered with snow or flooding.
You need your chicken coop to be tall enough so that the chickens are not exposed to drafts when they are on their resting bars at night. Again, therefore, you'll need higher walls to make sure the ventilation is high enough above the chickens to prevent drafts. Some chicken farmers build larger birdways and go through them themselves; others like to make an entire wall removable so they can get in and out with ease. This means that your chickens won't have enough space to use the floor space under the shelters if the chicken coop is only 3.5 feet tall.
When building a chicken coop, the goal is to build a structure that keeps your chickens safe from predators, moisture, drafts, diseases, overheating, chills, and leaks. If your farm has an elegant chicken coop of cherished chickens or birds that you can't live without, then a fence longer than 6 feet offers the best possible protection for your chickens. This is because only a few chickens live in this chicken coop and I only scoop their droppings out of the litter every day with a cat litter scoop. Many chicken farmers think that once you put up a chicken fence, your chickens are automatically safe.
Some chicken farmers, gardeners, and settlers say their chicken fence (and chicken corridor) only needs to be a few feet tall.
