I noticed yesterday that there is some bloody poo in the coop. Not a lot, maybe three spots. This is my first flock of 15 total. I've been on Google and read about some diseases. My flock is in between 8 and 10 weeks old. Everyone seems fine. It's really cold here today, so everyone is all fluffed up. Here's some poo I found this afternoon. I'm thinking I'm needing some medicine. I've lost a couple of birds awhile ago, and I don't want to lose anymore if possible. Thanks!
