Chicks hatched in incubators were after a period of handfeeding with
siblings fostered to pairs in captivity and later paired at an age of 2-5 months.
All pairs have been kept in aviaries with covered walls and meshed roofs and
had very little contact with humans. The birds have been observed through
one-way mirrors and the food (four-weeks chicken, day-old chickens and
quail) was presented through plastic tubes.
