I have 4 chickens and 1 roo. They are all about 15 weeks old. They all appear to be going through a molt but since this is my first flock, I am assuming this since there are feathers all over the pen and inside the coop. My Golden Buff girl is dropping very black stools that are like tar. I have been to the poop page but saw nothing like this. The other chickens are sometimes picking on her a little......not too badly but I just think she is lowest on the totem pole. She does not act sick and is eating and loosing feathers. Has anyone ever had this. It is so sticky, it is hard to clean. Everything else seems OK. I'd appreciate hearing anything you more expert chicken people would have to say. Thanks
