Ok, they aren't from my chickens, though... they have yet to give up the eggs for us. A friend of ours has backyard hens, too, and gave us a dozen eggs. Not sure what is in her flock, but they are smallish white eggs. I finally went to cook them today and 3 or 4 had this weird stuff inside. The whites were more pink and there was pink to red and dark brown to black inside them. Whatever it was actually stuck to the inside of the egg, too. I took a pic on my iPad but need to figure how to get it on here. They did not smell "bad" though, like a rotten egg. I discarded the eggs, contents, and the 2 that were in the bowl already (bummer) because I wasn't sure what it was. I thought about posting it on Facebook and asking, but don't want to insult my friend. I thought it was very nice of them to give us eggs, so I don't want to seem ungrateful.
