I have nine chicks about 5.5 weeks old. When they are getting their outside time in my garage, I am frequently running around with paper towel pieces to clean up poop, and while I see lots of normal poop I also see equal amounts of runny brown poop. I’m hoping it counts as Cecal poop and not diarrhea. I’m attaching one pic. It’s quite messy! I wasn’t expecting this much of it, but I guess with nine it’s hard to see who’s done it—whether it’s one chick or all of them taking turns.
