My Blackshoulder Peacock, Malibu, started molting in early July as far as I can remember, it may have been before that. I thought the hens were done laying for the year and he was done mating, but apparently not. After he had molted for a while, I came home and found four eggs within a week and a half or so. Two were broken because one hen decided to lay from the perch and one (probably same one) decided to lay from a high place in the coop where it rolled off and broke, so I was left with two eggs. I thought, well I might as well try to incubate them and see, not expecting anything, but sure enough, tonight was the 7th night and they have air sacs and blood vessels. Just wanted to share my experience in case anyone else is getting eggs and think they might be infertile. Go for it and try to hatch them.
