Chicken Coop Cost Calculator
— How Much Do You Need?

When it comes to chicken runs, drainage and stable footing are your two biggest priorities, and the right aggregate material addresses both at once. Pea gravel is a popular choice because its smooth, rounded texture is comfortable for chickens to walk on and easy for you to rake clean. Crushed stone, such as 3/4-inch clean crushed stone, packs down more firmly and creates excellent drainage for areas that see a lot of rain or have heavy clay soil underneath. If your run sits on particularly soft or poorly draining ground, a layered approach works well. A base layer of crushed stone handles drainage, while a top layer of coarser sand or pea gravel gives your birds a comfortable, clean surface to walk and forage on. Both options resist turning to mud in wet weather, which is one of the most common and frustrating problems backyard chicken keepers deal with. Getting the right material down from the start saves you a lot of cleanup and rework over time. Hello Gravel offers gravel and crushed stone for bulk delivery to your property. Use the Hello Gravel calculator to estimate how much you need based on your run dimensions, or reach out to the team if you want help choosing the right material for your specific setup.

The amount you need depends on the size of your run and how deep you want your material layer. For most chicken runs, a depth of 3 to 4 inches is a solid starting point. At 3 inches deep, one cubic yard of material covers roughly 100 square feet. So a 10-foot by 20-foot run, which is 200 square feet, would need around 2 cubic yards at that depth. If you want to go 4 inches deep for better drainage on clay-heavy or low-lying ground, plan for a bit more material. It is always better to have a little extra than to run short mid-project. Keep in mind that Hello Gravel delivers materials in bulk by the truckload. If your run is on the smaller side, it is worth thinking about other projects on your property at the same time, such as a path to the coop or a leveling base under the coop itself, so you can make the most of your delivery. The best way to get an accurate number is to plug your exact dimensions and target depth into the Hello Gravel calculator. If you are unsure what depth makes sense for your soil or climate, the Hello Gravel team is happy to walk you through it.

Poor drainage creates a chain reaction of problems that most chicken keepers do not anticipate until they are already dealing with them. When water pools under or around the coop, it creates persistently muddy conditions that are hard on your chickens' feet, attract flies and rodents, and cause the wood structure of the coop to rot much faster than it otherwise would. Wet bedding inside the coop is also a source of respiratory issues for your flock, especially during cooler months. A base of gravel or crushed stone under and around the coop helps water drain away quickly instead of sitting on the surface. Even a 4-inch layer of crushed stone under the coop footprint and throughout the run makes a meaningful difference, particularly in wet climates or on ground that does not drain naturally. Think of the material beneath your coop as infrastructure doing quiet but important work every time it rains. Getting that base layer right from day one saves you time, money, and a great deal of frustration down the road. Hello Gravel can deliver the gravel or crushed stone you need to build that drainage base properly. Reach out to the team or use the calculator to figure out how much your project requires.

The most frequent mistake is skipping site preparation entirely and placing the coop directly on bare soil. Bare soil compacts over time, drains poorly, and quickly turns muddy in wet weather. It also gives burrowing predators a much easier path under the coop and into the run. A second common mistake is choosing a low-lying spot that collects runoff from the rest of the yard. Even ground that looks relatively level can be a collection point for water during heavy rain. Over time, that standing water creates the exact muddy, unsanitary conditions you are trying to avoid. A third issue is using too thin a layer of material. A light dusting of gravel looks tidy at first but does not provide meaningful drainage or stability. Three to four inches of compacted gravel or crushed stone is what actually holds up over time. Skimping on depth usually means adding more material later anyway, so it is worth doing it right the first time. Taking time to grade the site, lay down an adequate base, and position the coop on well-drained, slightly elevated ground will pay off for years. If you are not sure how to assess your site or how much material you need to correct it, the Hello Gravel team can help you think through the plan before you order.

Placement makes a bigger difference than most people expect. The best spot for a coop gets some shade during the hottest part of the day, has good air circulation, and sits on ground that drains well after rain. You want to avoid the lowest areas of your yard, spots that sit in constant shadow and stay damp, and areas directly under large trees where debris and moisture accumulate. The ground surface under and around the coop plays a central role in how easy your setup is to maintain. A gravel or crushed stone base keeps the area from turning into a muddy mess, makes cleanup faster and easier, and helps deter animals from digging underneath the structure. If your preferred spot has soft, uneven, or sloped ground, fill dirt can be used to bring it up and level it out before you lay your gravel base. If you are working with a noticeably sloped yard, a modest amount of fill dirt can help you create a level pad first, and then your gravel base goes on top of that. Hello Gravel offers both fill dirt and a range of gravel options for exactly this kind of two-step site prep. The team can help you figure out what combination makes sense for your specific ground conditions.
