Is this poop normal?

One of my chickens refuses to come out this morning(it is cold). But under her was this poop. It looked differ from all the others. This is from my chicken with reproductive problems.

Just to weed out food... what kind of food are they being fed? Any treats that cause runnier poop like watermelon, cucumbers, etc.?

They’ve been eating layer pellets, black oil sunflower seeds, and anything they can find in their run. No super runny foods have been fed to them recently.
