Peahen (Pea) laid an egg on my porch.?

A peahen just laid an egg on my porch about an hour ago. There is no nest and the peahen hasn't come back. I live in an apartment complex, I would incubate it but I don't think I would be very well equipped for such a large bird. I called the Department of Fisheries and Wildlife and they directed to me a rehabilitation specialist and they told me there wasn't anything they could do about it because the Pea is not a native bird. I live in Florida, any suggestions on what I should do?
