does this poop look suspect?

[my beautiful girls]

this is from my one year old buff orphington, charlotte. she is acting fine. eating and drinking fine. laying eggs. the color is concerning. I have not seen any of my other girls have this color poop. the last 3 days right before she goes to bed, she does this. I think during the day its normal, but not sure, I do not see this when cleaning the run and coop daily. is it possibly a cecal poop? If it was internal bleeding she would be acting ill wouldn't she? I have not feed them any blueberries or red cabbage lately either. thank you.

Looks like Cecal poop to me. It can vary in color from light to very dark.

Have you been feeding any different treats or does she have access to compost, wood ash or dark soil like peat moss?
