Chicken has white poop

[Zombimigz]

One of my chicken's poops were oddly more white than normal starting yesterday. The above image is one from this morning and a dried one from last night. It might by nothing but just in case, I wanted to check if this could be some sort of disease or infection. Besides the poop, she seems her normal self and is eating/drinking.

I don't see anything abnormal. Poop can be different between chickens because of their eating preferences.

Those (paper?) strips - in general I would not put any colored paper products in to their run - only plain white (napkins/paper towels) or brown cardboard out of concern what might be in inks if they ingest it directly or once it composted and becomes a part of yummy worm.
