Hi there. One of my chickens had a larger than normal, very smelly poo/pee this morning. It had a few undigested food pellets and looked to be bloody. Not bright red like a cut but like a brick red color. There looked to be a solid white blob of poo in there too. We added a few new chickens almost 4 weeks ago and one of them died in her sleep last Monday so now I’m pretty nervous. All of them are acting fine, running around the yard. I don’t know which chicken it was because my back was turned. They are all between 5-6 months old. Any advice?
