Male peacocks use their elaborate tail feathers to attract females (peahens) and establish dominance over other males. When two males are kept in the same pen, they may constantly compete for attention from any peahen that may be present. This can result in frequent disputes, chasing, and even injuries.
To ensure the well-being and safety of peacocks, it is generally recommended to keep only one male per pen. This allows each peacock to have its own territory and reduces the likelihood of conflict. If multiple males must be kept together, providing a very large enclosure with ample space, multiple roosting spots, and separate feeding and watering stations may help to minimize aggression. However, even in these situations, it is crucial to monitor the birds closely and be prepared to separate them if necessary.
