I have never let my peahens set their own eggs, as they supposedly get broody (want to start sitting) after eight eggs, which they lay every other day. If you take the eggs, she will continue to lay up to 20 eggs. Also, if you use an incubator, many peafowl enthusiasts tell you that you will get low survival rates, that is because the peachicks are not as domesticated a chicken chicks and more dependent on their mother to tend to them. They won't learn to eat or drink, or not take a chilling bath in their drinking water. The answer however is simple. Peafowl eggs take about 28 days to hatch and chickens 21, 7 days after you have put the first peafowl eggs in the incubator put in a few chickens - when they all hatch together the peafowl will learn from the chickens. I't worked for me.
