Ok I've looked at poop chart not seeing anything like this what do y'all think?... everybody is acting good no change in feed other than they seem to be eating more since the cooler weather, weight is good, they free range...

Not sure where you are located but we have a thisel plant here that looks a lot like what's in that poop. Our flock checked it out at first when we got them but quickly learned pooping them out is not as yummy and now just ignore them. Not sure if something similar happened here.
