all of the sudden a white egg

What breeds do you have? That could well enough be a duck egg... just because you haven't been seeing her laying doesn't mean she isn't. Looks like it's from a duck to me.

 

What kind of chickens do you have, maybe you have a whiy=te egg layer or a mutt whos laying that white egg.

 

BTW aits easy to tell the difference between a duck egg and a chicken egg, duck eggs have a waxy feeling to them feel it with your fingers, you'll be able to tell the difference, or try to scratch it chicken eggs shell are more rough and have more pores compared to more smooth waxy feeling of the duck eggs.

 

It doesn't look white white to me. It may be a very light brown chicken egg, or it could be from your duck. Like Crash said, they'll have a waxy feel to them, they'll feel very different from chicken eggs.

 

Yeah if it has a glossy look to it its most likely a duck egg. What you can do to be 100% sure is check really early in the morning, laying is the first thing duck do in the morning, I go to work ar 4:30 and when I go check the nest the duck is usually already there laying, so check really early in the morning that way you'll make sure its her.

 

Quote:Its like a pearl white. Not really white white. It has a very glossy look to it I kept getting glare from the camera on it. Also I did check the feel and it feels silky and the chicken eggs have a rough feel to them.

Congrats! Your duck is laying and has obviously figured out the nest box too!
