I have 3 cambells, a pekin and a black and white swedish. This month I started getting eggs, two a day for the most part. They are chicken egg sized, one tends to be slightly bigger, but not much. Both are a light pink in color. I figured it was the cambells laying since the pekin should be a bit bigger. I didn't really give it much thought though, as I was just happy to get the eggs. Now I am getting 3 a day and one is black. It's the same size as the larger pink one, but it is almost completely dark black when I pick it up. When I wash it to get the mud off, it washes out to a charcoal grey in color. I had heard of different colored eggs before, but never black ones. We have gotten two black ones so far. I assume its the swedish laying, but not really sure. I'll try to get some picture tomorrow morning of before and after washing.
