An Omelette For A Mouse

I found a tiny white egg on the way home last night. I spotted it in the green grass of someone's lawn. I picked it up to examine it. I thought it was a white jellybean at first but I could see by the shape and subtle markings that it was an unhatched bird's egg. I carefully carried it home in my left hand while holding Lily's leash in my right hand. I wonder what the egg will become. An omelet for a mouse?
