We noticed yesterday blood in the brooder. One of our chicks is pooping blood Not sure which one it is. It is hard to tell on the barred rocks as there feathers are darker. Does anyone have an idea why and what may have caused this and what I can do to help the one that it is. Their bedding is of pine chips. And they are a month old now. Thank you in advanced. I know it is one of the percher ones just can't catch the little one who is doing it.
