My RIR roo has had "loose" poop since he was very young. It wasn't bad , I thought it was normal for him, so I didn't worry about it. The six hens are fine. I started feeding the flock (7 in all) Activia yogurt (with fruit - plain with probiotics isn't available here) three days ago thinking that would clear it up. Yesterday it was a little worse and today it is mosly liquid. I see no signs of worms. He is eating, drinking and acting normal. Gobbles up the yogurt and, this morning, warm oatmeal. Could the probiotics be making this worse? Should I be doing something else. They are all 19 weeks old. Well, above is what I'm getting when I try to insert a picture so here's what I'm seeing. There is a small amount of dark in the poop surrounded partially by a milky, thicker liquid and then a clear, running liquid. Thanks!
