This morning when I went out to the coop I noticed some poo with what appears to be blood in it. I could also see some grass in it. I didn't have my camera so I couldn't get a picture of that poo. I did get this picture of some poo that looks like it might have blood in it. The chicks are 9 weeks old and have been running around outside during the day in a 40' by 60' enclosed area for several weeks. They all appear to be alert and happy.
