What does a captive peacock eat?

Peacocks are omnivorous; in captivity feed bean cake, soybean, corn, wheat, sorghum, rice, greens, and grass. Note the green peacock is a first-class protected animal and private keeping is forbidden.

Blue peacocks can be farmed but need a special license and are not suited to residential areas. They need a proper environment and professional skill, so consider carefully before keeping.
