My brother works for the Montgomery Water Works and while they down in a pit he found these small, white, hard- shelled eggs. When I say small I really mean it. We can't understand how they got where they did seeing as the cover to the pit over laps and doesn't have any holes in the top. It's also flush against a brick wall. I was thinking that they might be hummingbird eggs because of the size, but I really have no idea what they could be.
