The math

  1. Area: 100.0 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic yards: 100.0 × 0.250 ÷ 27 = 0.93 yd³.
  4. Tons: × about 1.4 tons per yard = 1.3 tons.

The gravel calculator does this for any size.

Stone for a chicken run

Chickens scratch, so a run floor of washed stone 3 to 4 inches deep holds up better than bare soil. Grade the run so water runs out of it, and hose or rake the stone clean as needed.

Before the stone goes in

Remove sod and roots, level the area and slope it slightly for drainage. Install edging so the stone stays inside the footprint.

Ordering and delivery

Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. Round up by about 10 percent for compaction and uneven ground.

Tools for the job

A flat shovel, a steel rake, a wheelbarrow and a rented plate compactor cover most residential pads. A landscape rake or the back of a rake levels the top layer, and a long straightedge or a level string shows high and low spots before the final pass.

Measuring the area

Use a long tape and measure each side twice. If the ground slopes, measure depth at the high and low ends and average them. Irregular outlines can be broken into simple rectangles, triangles and circles; add the pieces for the total square footage before converting to tons.
