"The eggs of the moorhen are normally of a broad oval form and have
a small amount of gloss. The ground-color varies much, being creamy
white, pale greenish white, pale buff or pinkish buff. The markings
consist of specks, spots, and bold blotches of deep reddish brown, and
a few underlying pale purple spots. The combinations in which these
markings occur are numerous. In some, the markings are all small and
densely set over the shell; in others, spots are combined with huge
blotches which are often confluent. As a rule the larger end of the
egg is more thickly marked than the other parts. A few specimens are
devoid of all markings except some pale purple blotches. Examples vary
from 39.3 to 55 in length and from 27.9 to 36 in breadth." (Oates.)
