I was walking through a large field 2 weeks old and I came across a strange egg. There were no towers or trees anywhere near by so it couldn't have fallen. The egg was a bit larger than an average chicken egg an had a sort of off-white tint to it. The thing that surprised me the most was it's thickness! I thought someone dropped a ceramic egg at first! I literally had to hit it against a metal pole in order to crack it in half! The yolk was VERY dark orange. What kind of egg could this be? Also, the field was far from my house and wasn't mine. It looked somewhat like a lawn that hasn't been cared for in years except much larger. Please help!!
