In the real world, all bird species (and virtually all reptile species) will lay unfertilized eggs under the proper circumstances. For birds, those circumstances are really quite easy to achieve if you mean to. Pairing (including two or more females, no males required), nesting, and environmental triggers including light and temperature are all that's required.
So, my suggestion is a simple enough one. Can we have domesticated birds laying unfertilized eggs? I would assume for the sake of balance, these eggs would have various downsides over the incredible'tude that is chicken eggs such as a much slower laying cycle or specific environmental requirements as noted above.
