Quoting from page 74 in Ehrlich, Dobkin, & Wheye (1988) "Birder's Handbook.:" "Clutches of 15-50 result from 2-10+ females contibuting to individual nests..." Apparently this "dumping" increases with increased density of nest boxes, although the female will try to repel the parasitizing females from her nest.
