The mother is fed by her mate through a slit in the seal. The clutch consists of one or two eggs, which she incubates for 38–40 days. The female voids feces through the nest slit, as do the chicks from the age of two weeks. [30] Once the female emerges from the nest, the chicks seal it again. [7] The young birds have no trace of a casque.
