The females generally make nest within on to 2 miles from the Lek itself, in thick clumps of grass that cover the eggs from both the air and the ground.

It is usually lined with dry grass, twigs, and feathers. The females incubate the eggs alone, and after hatching, the chicks are able to feed themselves immediately, though they spend about half of the day for the first few weeks sheltered under the hen’s wings.
