I was weeding one of my trees in the front landscape, and found this what I think is a bird egg. The dirt above it was not loose - it was undisturbed ; there was probably about 2 inches of mulch and dirt above it. Really odd. It does not look like a reptile egg, it is hard; I use my phone light to see into it, but it does not look fertile.
I know a lot about a little, and a little about a lot.
