Today we gathered this egg which we have never seen before. At first I thought it was one of our somewhat new chickens that we got from a friend, but it's much smaller than a regular chicken egg. I do have one female Magpie that lives with the chickens so I was wondering if it was her, but I thought their eggs were white!? Any ideas? The egg is darker than anything I have seen Here it is next to a regular chicken egg. It's definitely small!!
