All white poos?

[Rainbow Dash]

Well, I've been noticing the last couple of days, that my mix bantam has been pooing strangely. Her poos are all white! She hasn't been acting depressed though, and her friends aren't experiencing this either.
I'm stumped. Anyone know what this could be?

have you cut one in half? is it white all the way through?
The white is the urea, the kidney waste. i think it's urea crystals.
I do not know how odd pure white is, but i have chickens that have white covered poo.

Bump. Anyone?

Anyway, her poops sometimes have all white in the center, sometimes there are traces of brown.
P.S. This isn't the bantam who has just started laying, BTW.
