Chicken Run tips
Gravel in a run stops the ground from turning into a muddy, smelly mess. Washed stone of about 3/8 to 3/4 inch drains well; some keepers add sand or wood chips on top in part of the run for dust bathing.

Prep
Remove sod and roots, level the area and slope it slightly for drainage. Install edging so the stone stays inside the footprint.
Getting it delivered
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
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.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
