one of the four chickens started releasing a dark, very liquid poop about four days ago. it had been very cold. I have only see shat of liquid sort once and it has white matter in it. i'm posting a photo of it below. It's the the shat on the upper right (dark brown on apple tree leaf) is the shat i saw all over the yard and porch. if someone knows of an illness or condition that caused this, please let me know. it might still be going on and i'm just not seeing the shat.
i'm hoping one of the chickens are sick.
