Nest On the ground, they roost high in trees.
Also 1 year old peacocks look alot like peahens.
they dont get the colors until 2 and the long train until 3
This happens alot, people buy them and when trying to break them to free range. Off they go to a near by chicken flock,or a new home. I sell many peahens to people who have a peacock show up, looking for love.
