When would it be best to separate our two week old peachicks from their mother?

Leave your family or “bevy” of peafowl together until they are at least two months old, particularly as the young peachicks develop slowly and they will continue to roost close to their mother up until this age. Keep them in their aviary through this period, as they will be much safer there.

You should then be able to sex them by this stage, which can be helpful in finding them new homes. The taller ones are likely to be peacocks, as may be confirmed by the chestnut rather than dark brown coloration of their long flight feathers across the back of the wings. Even so, it will be at least three years until they develop their magnificent train which they use for display purposes.
