Silly question, but are you sure they were fertile. My peahen also laid for the first time this year, but we never saw her "with" the male and every egg she laid was not fertile. I'm not sure, but I don't think they were old enough - the peacocks , that is. I have incubated peafowl eggs before (that's where I got all my guys, except for one) so I know that my incubator works well. I posted a link to an article on this in a previous post. I'll find it and send to you.
