Speckled egg?

[X2Farm]

So I've got this one hen, Big Mama, the only thing that stands out about her, is her split beak (just the tip) Other then that, she looks like a normal RIR. She laid an egg today, and the egg is a light brown with darker speckles on it. I've got some others that are just the normal light brownish color....

Is it possible there's a strain of something else in the RIR hen thats laying these eggs? One of the girls even has some white in her wing feathers

Or maybe somethin is just wonky at the "paint booth"

Its no bother, really, I'm just curious more then anything

The Younger the bird, the more likely it will lay a speckled egg I believe welsummers lay all speckled eggs.
