I would do what Deerman said for the eggs. That way you can still see the peahens incubate the eggs but have a fallback if they end up not setting the eggs. That is what I am planning on doing this year because I really want peachicks but I also want my peahens to incubate some eggs too, so I am going to incubate the first clutches, and after that point whatever the peahens want to do they can do.
