Yep.
The white egg is hers? Chickens usually lay eggs of their color, right? I've never had chickens, just beagles. Why would eggs of two different birds get so close? Aren't they usually possessive of their own eggs?
Not so much to do with the color of the plumage. You can tell the color of the eggs the chicken will lay by the color of the earlobes. My wife likes the colored eggs so we have Easter Eggers, Ameraucanas, Marans and others. I like the crazy hair so we also have Silver Laced Polish (named Beaker after the Muppets Show), Silkie Bantam, Gold Laced Wyandotte, Plymouth Rock and a Frizzle (named Fajita).
Out of 17 birds, we only have two nesting boxes, they all tend to lay in the same box. Sometimes a girl will get broody and want to lay on the eggs, then we have to put her in chicken jail for a few days to break her.
