Hello, This is my first post. I have a chick (1 of 5) that I think is approx 3 weeks old. It periodically has blood in it's stool. any ideas on what the problem may be? The stool is runny. I think its just one of the chicks but they are all in a tub with a heat lamp, so I can't be sure. but the blood is not in all the stool, just a small amount so I'm guessing it's a 1 chick problem.
