Trying to figure out the relative likelihood that one of our chickens laid two eggs today and that our ducks started laying. The last couple days we've had an odd looking egg. A little longer than a normal chicken egg but about the same width. We have a chicken that occasionally lays them larger though (double yolks) so they aren't huge or anything. But today we got eight eggs, and we only have seven pullets/hens. We have three ducks that should be about the right age. But they're runner ducks and these eggs aren't white. They're a pale brown.
